The former Prime Minister Gordon Brown says the next leader of the Labour Party needs to recognise voters' demands for change and support more powers being given to the North of England.
Mr Brown wouldn't be drawn on his choice to replace Jeremy Corbyn, while speaking at a Newcastle conference today, aimed at promoting the union. However, he told ITV News Tyne Tees what he thinks they should focus on:
Just three candidates remain in the race to become Labour's next leader, with party members due to start voting on 24 February.
On Sunday the Labour Leader and Deputy Leader candidates will be addressing their party members at a hustings in Durham.
There is a big task ahead for the successor to Jeremy Corbyn, as they will need to bring the party back from its worst electoral defeat, in terms of House of Commons seats, since 1935.
We'll find out who gets the top job on 4 April.
But how much do we know about the three remaining candidates?
To find out, we sent our Political Correspondent Tom Sheldrick to one of the North East's Labour constituencies lost to the Conservative Party in December's general election.
Who are the three remaining Labour leadership candidates?
Rebecca Long-Bailey, MP for Salford and Eccles
Lisa Nandy, MP for Wigan
Keir Starmer, MP for Holborn and St Pancras
