Andy Burnham has pleaded with Labour activists to fight the Tories rather than Tony Blair as the leadership contest enters its last full day.
The shadow health secretary used his final full speech of the campaign to issue a thinly-veiled warning about the "credibility" of left-wing frontrunner Jeremy Corbyn.
Mr Burnham said: "I have no doubt that, whoever wins, Labour will change quite profoundly, but we need to ensure it is the right kind of change. Change that unites, puts us back in touch with the public and can win a general election. That is what I am offering.
"Labour needs a leader ready to fight the Bullingdon Boys, not Tony Blair and the battles of the past. With your support, I will be that leader and give Labour a radical, but credible, Prime Minister-in-waiting."
Votes in the contest have to be in by midday tomorrow, with the result due to be announced on Saturday.
