LONDON - Britain's main opposition leader Jeremy Corbyn apologized Sunday for waging a disastrous campaign that handed Prime Minister Boris Johnson a mandate to take the UK out of the EU next month.
But the veteran socialist defended his far-left platform and blamed the media for helping relegate his century-old party to its worst performance since before World War II.
"I will make no bones about it. The election result on Thursday was a body blow for everyone who so desperately needs real change in our country," Corbyn wrote in the Sunday Mirror newspaper.
"I wanted to unite the country that I love but I'm sorry that we came up short and I take my responsibility for it."
Thursday's snap general election turned into a re-run of the 2016 EU membership referendum in which Johnson championed the Brexit cause.
Johnson now commands an 80-vote majority in the 650-seat House of Commons - a margin last enjoyed by the late Tory icon Margaret Thatcher in the 1980s.
A sombre but combative Corbyn said Friday that he will step aside once Labour completes a period of "reflection" about its mistakes.
The party is expected to have a new leader in place before England votes yet again in local polls in May.
Yet the 70-year-old has no clear successor after a year of infighting between a protectionist old guard backed by the unions and more metropolitan members with pro-European views.
Corbyn tried to find a balance between the two camps by taking a neutral position on Brexit - a decision that Labour finance spokesman John McDonnell proved to be fatal.
"What we tried to do is bring both sides together and we failed," McDonnell told the BBC.
Labour's campaign was also dogged by allegations of anti-Semitism that forced a handful of senior lawmakers to resign.
Corbyn tried to shift the campaign's focus on bread-and-butter social issues important to Labour voters.
"But despite our best efforts, this election was ultimately about Brexit," Corbyn admitted in his letter.
"The Tory campaign, amplified by most of the media, managed to persuade many that only Boris Johnson could 'get Brexit done'," he said in reference to Johnson's campaign slogan.
"We will learn the lessons of this defeat."
The soul-searching and recriminations have been accompanied by questions in other Western countries about how far left traditionally liberal voters are prepared to go.
"Look what happens when the Labour party moves so, so far to the left," U.S. Democratic presidential hopeful Joe Biden warned Friday.
Yet Corbyn signaled Sunday that he wanted to leave behind a radical legacy that keeps Labour's focus on vast social spending and redistribution of wealth.
He came under intense criticism from more moderate supporters Sunday for claiming that his platform ultimately proved right.
"I am proud that on austerity, on corporate power, on inequality and on the climate emergency we have won the arguments and rewritten the terms of political debate," he wrote in a separate column in The Observer newspaper.
Several prominent Labour members who are viewed as potential leaders sharply disagreed.
"It's time to try something different, rather than re-enacting old battles," lawmaker Jess Phillips wrote in The Observer.
"Everywhere I campaign, I heard the same thing. It was less about Brexit and more about belief. In these places of generations of Labour voting, they did not believe a Labour government would or could deliver for them."
Labour parliamentarian Lisa Nandy agreed that the party had "lost touch with the day-to-day... experience of many of the people we want to represent".
"If we are going to represent the country, we need to understand it, to see it as it really is, not how we might imagine it to be," she wrote in The Observer.
