LONDON (AP) — The Latest on Britain's historic vote to leave the European Union (all times local):
French President Francois Hollande said he profoundly regrets the British vote to leave the European Union, but that the union must make changes in order to move forward. In a brief televised statement, Hollande said the vote will put Europe to the test, and he called for bolstering security and industrial policies.
He also called for reinforcement of the zone of countries that use the euro.
He said, "To move forward, Europe cannot act as before."
Boris Johnson says the vote to leave the European Union gives Britons a "glorious opportunity" to take control.
He said Friday there is no need for haste in negotiations.
He said the vote means Britain will be able to set its own taxes and control its own borders.
"It was a noble idea for its time; it is no longer right for this country," Johnson said of the EU.
He praised Prime Minister David Cameron as an "extraordinary politician" and said he is "sad" to see Cameron resign.
The former London mayor did not say Thursday if he plans to contend for the Conservative Party leadership.
European Union leaders are warning Britain to leave the EU quickly and avoid prolonging uncertainty.
The presidents of the EU's main institutions said in a statement Friday that they expect London to act on the decision to leave "as soon as possible, however painful that process may be."
The four — EU Council President Donald Tusk, Commission President Jean-Claude Juncker, Parliament President Martin Schulz and Dutch Prime Minister Mark Rutte — said that "any delay would unnecessarily prolong uncertainty."
Prime Minister David Cameron has suggested that formal notification of Britain's departure might not come before October.
French far-right leader Marine Le Pen says pro-independence movements in the European Parliament will meet soon to plan their next move after the British vote to leave the European Union.
With a broad smile on her face, Le Pen said her National Front was the only political party in France to take the possibility of a British exit seriously, and she reiterated her call for a similar referendum in France, calling it "a democratic necessity."
"The British people have given to Europeans and to all the people of the world a shining lesson in democracy," Le Pen said.
Le Pen, who is a member of the European Parliament, is also positioning herself to run for president of France in elections next year.
Slovak Prime Minister Robert Fico says the EU will have to react quickly to Britain's decision to leave.
Fico, whose country is taking over the rotating EU presidency in July, says the bloc's key policies have to change.
In a Friday statement Fico says: "Huge numbers of people in the EU reject the EU's immigration policy, there's big disappointment with the economic policy."
Fico says the EU needs to be bold enough to say that those EU policies need "a fundamental change."
Fico is a vocal critic of the EU's approach to the migrant crisis, in particular to the plan to redistribute the refugees in member states.
He says that during the presidency, he is ready to provide room for informal debates on the bloc's future.
Poland's foreign minister says that if the model of a political form of the European Union keeps being pushed, the common European project may end in "catastrophe."
Witold Waszczykowski said Friday that European politicians should think more deeply about whether to continue pushing for a political form of the union.
"If there is a deeper reflection, a pause in the pushing of this French-German model, then the union will survive. But if the eurozone is forced, and the eurozone creates some new institutions, its own budget and treats the whole European Union as a facade, then it may all end in a catastrophe."
He said other countries may now use referendums to "blackmail the EU to win a change in their status."
The leader of the ALDE liberals in the European Parliament says it is necessary for Britain to officially declare its intention to leave the European Union and not wait until October when Prime Minister David Cameron has said he will step down.
Guy Verhofstadt said he found it "unacceptable ... that he is going to wait until October and let it to his successor."
Despite the referendum result, Britain can choose the moment when it officially tells its European partners that it will leave, officially kicking off a process that could take two years or longer.
"It would be possible that in the whole of 2016 there is no notification of the British decision, what is against the will of the British citizens," Verhofstadt said.
He warned that would only extend the market turbulence that started immediately after the results were known.
NATO's chief says the British vote to leave the European Union shouldn't affect its status as a reliable and key member of the U.S.-led military alliance.
"As it defines the next chapter in its relationship with the EU, I know that the United Kingdom's position in NATO will remain unchanged," NATO Secretary-General Jens Stoltenberg said Friday in a statement. "The U.K. will remain a strong and committed NATO ally, and will continue to play its leading role in our alliance."
British voters' decision on Thursday to exit the 28-nation European Union sent shockwaves through Europe and around the world.
"Today, as we face more instability and uncertainty, NATO is more important than ever as a platform for cooperation among European allies, and between Europe and North America," Stoltenberg said. "A strong, united and determined NATO remains an essential pillar of stability in a turbulent world, and a key contributor to international peace and security."
The European Central Bank says it is "closely monitoring financial markets" in the wake of the British vote to leave the European Union.

It also said it was staying in close contact with other central banks.
Otherwise the ECB did not immediately announce any new measures. The bank already provides short-term cheap credit to banks in any amount at regular intervals, and has pumped more cash into the system through a bond purchase program aimed at raising inflation.

He says the message of the British voters is that politicians need to deal head-on with the problems facing the EU like high unemployment, the migrant crisis and social security issues.
He says the British "didn't vote against Europe, but against the way it's been configured up to now."
Spain's acting Prime Minister Mariano Rajoy says his country has received Britain's decision to leave the European Union with sadness, adding that "it ought to make all member nations rethink."

In a reaction on Facebook, the Czech leader said Friday the EU has to work to minimize the damage to EU and Czech citizens.
"The EU has to change. Not because Britain left, but because the European project needs much stronger support from citizens."
"The EU is for us, the Czech Republic, the best possible guarantee of stability, peace and prosperity."

Analysts are cutting their estimates for Britain's economic growth after the country voted to leave the European Union, ushering in a period of high uncertainty that is likely to shake businesses, consumers and markets for some time.

Archer expects the Bank of England to switch from hoping to raise interest rates soon to cutting them by a quarter point to 0.25 percent before long.
He says: "Major economic and political uncertainty will be a fact of life for some considerable time, likely weighing down markedly on business and household confidence and behavior, so dampening corporate investment, employment and consumer spending."
Analysts at Capital Economics have the same growth forecasts for 2016 but are more hopeful about 2017, seeing 1.5 percent growth.

The U.K. is the first major country to decide to leave the bloc, which evolved from the ashes of the war as the region's leaders sought to build links and avert future hostility.
Financial authorities around the world have warned that a British exit will reverberate through a delicate global economy.
Scottish leader Nicola Sturgeon says her country cast an "unequivocal" vote to remain in the European Union — a result that raises the specter of a new referendum on Scottish independence.

Britain's vote to leave the 28-nation European Union is likely to cost Prime Minister David Cameron his job.
The leader of the ruling Conservative Party had staked his reputation on keeping Britain in the EU.
Former London Mayor Boris Johnson, the most prominent supporter of the "leave" campaign, is now seen as a leading contender to replace Cameron.
Cameron promised the referendum to appease the right wing of his own party and blunt a challenge from the U.K. Independence Party, which pledged to leave the EU. After winning a majority in Parliament in the last election, Cameron negotiated a package of reforms that he said would protect Britain's sovereignty and prevent EU migrants from moving to the U.K. to claim public benefits.
Critics charged that the reforms were hollow, leaving Britain at the mercy of bureaucrats in Brussels and doing nothing to stem the tide of European immigrants coming to the U.K. Those concerns were magnified after more than 1 million people from the Middle East and Africa flooded into the EU last year.
The result of the British referendum has shocked the markets but delighted "leave" campaigners.

As results poured in Friday morning, a picture emerged of a sharply divided nation: Strong pro-EU votes in the economic and cultural powerhouse of London and semi-autonomous Scotland were countered by sweeping anti-Establishment sentiment for an exit across the rest of England, from southern seaside towns to rust-belt former industrial powerhouses in the north.
Deputy Labour Party leader John McDonnell says "a lot of people's grievances are coming out and we have got to start listening to them."
Britain has entered uncharted waters after the country voted to leave the European Union, according to a projection by all main U.K. broadcasters. The decision shatters the stability of the continental unity forged after World War II in hopes of making future conflicts impossible.
The decision raises the likelihood of years of negotiations over trade, business and political links with what will become a 27-nation bloc. In essence the vote marks the start — rather than the end — of a process that could take decades to unwind.
The "leave" side was ahead by 51.7 percent to 48.3 percent Friday morning with more than three-quarters of votes tallied, making a "remain" win a statistical near-impossibility.
The pound suffered one of its biggest one-day falls in history, plummeting more than 10 percent in six hours, from about $1.50 to below $1.35, on concern that severing ties with the single market will hurt the U.K. economy and undermine London's position as a global financial center.
