POLL: Who do you want to be the next Labour leader? | Politics | News
Meanwhile, Wes Streeting quit as health secretary and said he would stand in any race.
He hit out at the incremental approach of Sir Keirโs administration and has called for Britain to rejoin the EU.
Former deputy prime minister Angela Rayner is clear for a potential bid after she resolved her tax affairs with HMRC.
She resigned last year after it emerged she had underpaid stamp duty on a seaside apartment.
Ex-Labour leader Ed Miliband has denied suggestions he would be interested in another go at the job.
Elsewhere, armed forces minister Al Carns could be a dark horse leadership contender.
He has reportedly said he would stand in a contest and called for the return to Labourโs roots to support the working classes in an article in the New Statesman magazine entitled How Labour Can Win Again.
But the Prime Minister has insisted he will not โwalk awayโ from Downing Street.
Any leadership hopefuls will need to secure the backing of 81 Labour MPs to mount a challenge against Sir Keir.
