Former prime minister Gordon Brown has said Labour can only deliver on its principles in power as he made a high-profile intervention in the leadership contest with a keynote speech.
Mr Brown said he did not aim to attack any of the candidates in a speech that set out to clearly distance himself from support for frontrunner Jeremy Corbyn.
Lance Price, the former director of communications for the Labour party, has told ITV News he hopes those voting in the party's leadership election will listen to Gordon Brown.
Mr Price said he believed the former prime minister was able to "reach parts of the party" that others, like Tony Blair, could not.
Former PM avoided naming any Labour leadership candidates in his speech, but appeared to make a veiled warning against electing Corbyn.
A poll rates Jeremy Corbyn as the leadership candidate both most likely to improve Labour's fortunes and damage the party's chances.
