Labour peer Lord Blunkett has said that Labour needs to work out what it stands for before it embarks on a search for a new leader.
The former cabinet minister said he was "not in favour" of Jeremy Corbyn remaining at the head of the party long-term but added "throwing eggs at him at the moment actually isn't going to change anything".
Until the Labour Party actually knows what its new leader stands for and how that's going to relate both to the instincts of the electorate and the reality of globalisation, we are not going to get anywhere.
That is the most enormous challenge for all social democratic parties around the world and I don't have a simple answer.
Lord Blunkett spoke out on Radio 4 Today programme as Mr Corbyn faces growing calls to resign.
He added: "Jeremy isn't the problem. His project and those around him are the problem."
The leader of the UK's biggest trade union has said the country is 'riven' as a result of the EU referendum.
Len McCluskey told ITV News that the trade unions can help broker a peace deal and reunite the party now the "coup has failed".
Labour leader Jeremy Corbyn said he would 'reach out' to MPs that oppose his leadership but said they should 'respect democracy'.
