The U.K. could stay in a reformed European Union despite the Brexit vote, according to former Prime Minister Tony Blair.

In a statement posted to his foundation's website, Blair said every alternative for the U.K.'s future should be made clear to the British people, which would "sensibly include the option of negotiating for Britain to stay within a Europe itself prepared to reform and meet us half way."

He said the victory of Emmanuel Macron in France had changed "the political dynamics of Europe" and "reform is now on Europe’s agenda," adding that "European leaders, certainly from my discussions, are willing to consider changes to accommodate Britain, including around freedom of movement."

The former Labour leader admitted that "Brexit will happen" if "the will of the British people remains as it was last June." But he said "as we know more about what Brexit means, our ‘will’ changes."

He also emphasized the importance of the single market and why Britain should stay in it, saying that doing so would mean "the economic damage of Brexit will be limited."

In the statement, released alongside polling on whether people in the U.K., France and Germany consider themselves part of the political center, Blair didn't hold back on the state of British politics. "There is a slightly anarchic feel to our politics intensified by the realization that the government is weak and drifting."

He had (some) kinder words for current Labour leader Jeremy Corbyn, saying that the June election result was "remarkable."

"I pay tribute to Jeremy Corbyn’s temperament in the campaign, to the campaign’s mobilization of younger voters and to the enthusiasm it generated," Blair, normally a Corbyn critic, said. "The Corbyn campaign was a positive factor in the election result; but the determining factor was the Tory campaign."

However, he said a Corbyn-led government after Brexit would leave the country "flat on our back."

“If a right-wing populist punch in the form of Brexit was followed by a left-wing populist punch in the form of unreconstructed hard-left economics, Britain would hit the canvas, flat on our back and be out for a long count,” he said.

"I would hesitate before saying that all those who voted Labour voted to make him [Corbyn] prime minister, or that they supported the body of the program rather than its tone."

Warning that the Tories would not make the same mistakes in future campaigns, Blair said the Labour Party would need to fill the "progressive center" with "a radical policy agenda."
