Following the dramatic resignations of Chancellor Rishi Sunak and Health Secretary Sajid Javid last night, the list of departures grew to more than 40.

Bookmaker Boyle Sports said Mr Johnson was now 1/10 From 2/1 to leave Downing Street. Johnson supporters and optimists can get odds of 6/1 about him still being in the role on 1 January.

The new chancellor Nadhim Zahawi is expected to push for early tax cuts, a reversal of the corporation tax rise to 25% from next April, and a further cut in fuel duty as he tackles a number of severe challenges. Inflation is running at a 40-year high, the cost of borrowing is likely to rise further and the economy is poised to enter recession.

The FTSE 100 closed in positive mood, up 82.3 points at 7,107.77, but the political uncertainty combined with the strength of the dollar has pushed sterling 0.4934% lower to $1.1889. Earlier it fell to $1.877, new low since the early days of the pandemic.

However, talk of a summer emergency budget is running alongside speculation of an early general election.

Following Prime Minister’s Questions, Mr Javid delivered a resignation statement to MPs in which he said he had spent many months giving Mr Johnson the “benefit of the doubt”, but there was a point when “enough is enough”. Rishi Sunak has no plans to make a statement.

Mr Johnson faced a volley of criticism and demands to resign, but responded by stating: “The job of a PM… is to keep going! And that’s what I’m going to do.”

After being grilled at PMQs, Mr Johnson faced the Liaison Committee which is seeking responses to the impact of the war in Ukraine on the UK, the government’s response to the rising cost of living, integrity in politics, and the rule of law.

The Committee is made up of the MPs who chair all the other select committees (health, education, defence etc).

The sessions usually last for around two hours and give MPs the chance to question Boris Johnson on all sorts of issues.
