Tony Blair has not pulled his punches in a series of attacks on the left-wing candidate for the Labour leadership election.
He told people who wanted to vote with their heart for Corbyn to "get a transplant" in a major speech today, and admitted that even if he could win on a left-wing platform, he wouldn't want to.
Calls to halt the Labour leadership race have been branded "unhelpful" after reports emerge of alleged "hard-left infiltration" of party.
Corbyn urges his party to be 'true to its roots' and offer 'a credible alternative' as the race to become new Labour leader continues.
"I can't believe that he said it," said Blair's former deputy Lord Prescott, who begged Labour to debate policies not personalities.
