TONY BLAIR’S attack on Jeremy Corbyn backfired badly yesterday, unintentionally sparking a rush of support for the left candidate’s Labour leadership campaign.

Mr Corbyn’s campaign team revealed that, in the hours after the former prime minister’s outburst, their fundraising efforts had soared past a £45,000 target.

They told the Morning Star that they were inundated with new volunteers, receiving over 1,000 emails from people offering their time to support the campaign.
