Britain's pro-Conservative newspapers on Sunday crowed that socialist Jeremy Corbyn's crushing leadership victory would condemn the Labour Party to the opposition for a long time, while leftist media hailed the win.
"Bye Bye Labour!" screamed a front-page headline in the Sunday Express and the Mail on Sunday published a picture of the new anti-austerity firebrand next to the words "Red and Buried".
"Death of New Labour," said the Sunday Telegraph, referring to controversial former prime minister Tony Blair's famous brand from the 1990s.
"Labour isn't dead, Blairism is. Jeremy Corbyn finally killed it," the paper said in an editorial that said that "boring Blairites" had been vanquished.
The Sunday Times also picked up on the splits in the party and several figures who have said they will not serve under his leadership, with the headline: "Corbyn sparks Labour civil war".
Corbyn won with a landslide 59.5 percent announced on Saturday, far ahead of his three more centrist rivals Andy Burnham (19 percent), Yvette Cooper (17 percent) and Liz Kendall (4.5 percent).
The Independent on Sunday referred to Corbyn's appeal in his victory speech to new young Labour supporters and returning former members, with a headline saying: "Welcome to the party, welcome home".
Guardian columnist Rafael Behr called Corbyn's election an earthquake "off the political Richter scale", pointing to the role of young people not previously involved in politics.
"Blairism is buried beneath the rubble and a different structural and cultural divide has been revealed," he wrote for the pro-Labour daily.
"It is between established Labour... and insurgent Labour, a complex hybrid of organised coup by dogged old warriors of the left and spontaneous, organic uprising by idealistic new recruits."
A special victory edition of the socialist Morning Star newspaper cheered his triumph.
"Jeremy Storms to Victory", said the paper, stressing that Corbyn had won with 59.5 percent of the vote compared to Blair's own leadership election with 57 percent in 1994.
Blair went on to win three successive general elections for Labour but is unpopular among leftwingers in the party because he led Britain into war in Iraq.
