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.
Gordon Brown has called for Labour to remain a party of power and not protest in order to "make a difference in people's lives".
ITV News Political Correspondent Libby Wiener has tweeted:
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.
