Here, The Sun looks at the runners and riders for the biggest jobs in government.

Chancellor

Ever since returned to Westminster, one question has dominated politics: who will get the keys to No11?

For weeks, looked like the favourite.

The former Labour leader has played a key role in Burnham’s rise and is regarded by allies as one of the Government’s most effective Cabinet ministers.

But his promotion has also alarmed MPs, advisers and market watchers, who see him as too closely associated with Labour’s soft left and worry his commitment to net zero could unsettle investors.

His supporters have insisted he is fiscally disciplined and have been pointing out there is little in his ministerial record to suggest he would embark on a borrowing spree.

However, concerns over market confidence are understood to have persuaded Burnham that Miliband may not be the right person for the Treasury.

Home Secretary is now widely tipped to become Chancellor despite wanting to remain at the .

Seen as being on the right of the Labour Party, she is viewed as a reassuring choice for the .

The biggest question mark is her lack of economic experience.

Foreign Secretary

has spent weeks fighting to keep hold of the Foreign Office.

During her first year in the role, she has built what allies describe as a strong working relationship with US Secretary of State Marco Rubio.

But if misses out on the Treasury, Burnham could hand him the Foreign Office as a consolation prize.

His brother David Miliband was also rumoured to be in line for the job – but The Sun reported last week he is actually eyeing the role of US ambassador in .

Former Defence Secretary , who extraordinarily quit ‘s Government over the defence investment plan, has also been tipped for the job.

Defence Secretary

Dan Jarvis only took over as Defence Secretary a matter of weeks ago after replacing John Healey.

At the time, many in Westminster thought he had inherited a poisoned chalice as ministers scrambled to find billions to fund Labour’s ambitious Defence Investment Plan.

Jarvis managed to secure a little bit extra cash from the Treasury and won praise for getting the DIP off the ground.

The former South Yorkshire Mayor is also seen as politically close to Andy Burnham, with the pair having worked together as metro mayors.

It has made him one of the ministers most likely to survive the reshuffle – although Healey is still seen by some as a contender if Burnham opts for experience.
