PHILIP Hammond’s confirmation he will resign if Boris Johnson becomes prime minister has prompted fresh talk about who will succeed him as Chancellor and who will be promoted or demoted in the Cabinet.

The Home Secretary Sajid Javid is seen as a likely successor to Hammond. He made it to the final four in the Tory leadership race and backed Johnson when he exited the contest.

There is speculation about whether David Mundell will remain in his post as Scottish Secretary.

The Scots Tory MP has previously suggested he would not serve in a Johnson-led cabinet.

In December last year, asked on BBC’s Sunday Politics if he would serve if Johnson became PM, he said: “Given my views about Mr Johnson which are well known that would be extremely difficult. Mr Johnson and I don’t agree on a whole range of issues and I don’t see myself being able to serve in that way.”

Yet when ITV Border confronted him with those words in June Mundell replied: “Yes, but it was not a ruling out of serving,” he said. “I have never explicitly ruled out that [sic].”

There is talk that Michael Gove may be in line for promotion.

The Environment Secretary was once a close ally of Johnson, but their relationship was severely damaged in June 2016 when Gove’s decision to stand for the leadership to succeed David Cameron scuppered his rival’s campaign.

Gove made it to the final three in this year’s leadership race, before being eliminated.

A source in Jeremy Hunt’s camp last month warned of the potential for “personal psychodrama” were Johnson and Gove to end up fighting it out as the final two for No 10. But there has been speculation that Gove may be brought back into the fold, with a source telling the Sun on Sunday his “outstanding ability ... won’t be wasted” when it comes to a cabinet team under Johnson. There is speculation the Scot could be appointed Northern Ireland secretary or communities secretary.

All eyes will be on what role Foreign Secretary and leadership rival Jeremy Hunt, who campaigned to remain in the EU, will have. According to reports, Johnson has told friends he wants a Brexiteer in the post – which could mean a promotion for defence secretary Penny Mordant or Attorney General Geoffrey Cox – but is being counselled by some to keep Hunt.

Ministers who are likely to leave government include International Development Secretary Rory Stewart, Business Secretary Greg Clark and May’s de facto deputy, Cabinet Office minister David Lidington, who initially backed Stewart in the contest.
