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.
Jeremy Corbyn will today set out his plans for "better business" promising to stand up for small businesses and clamp down on corporate tax avoiders.
It comes as former prime minister and chancellor Gordon Brown prepares to give a speech on the future of the Labour Party this afternoon.
Among the proposed policies are a freeze on tax rates for small businesses, a national investment bank, fair rents for local shops and more resources for HMRC to tackle corporate tax avoidance.
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.
