The next prime minister of the United Kingdom will be announced later today, September 05, following a grueling, and at times bitter, leadership contest within the ruling Conservative Party.

Former Finance Minister Rishi Sunak or current Foreign Secretary Liz Truss will emerge the UK’s new prime minister, the CNBC reports.

Truss is the frontrunner, while Sunak is expected to come second.

The announcement is expected at 12.30pm, London time and will be delivered by Graham Brady, the chair of the 1922 Committee, which is a group of Conservative Members of Parliament who aren’t government ministers.

The leadership election was triggered when current Prime Minister Boris Johnson announced he would be resigning on July 7.

It came after a wave of ministers and backbenchers resigned, with many voicing a lack of confidence in their party leader.

Johnson has stayed on as caretaker PM while the party decided between the candidates.

He has not yet formally resigned from office, as he must first attend an audience with Queen Elizabeth II to officially inform her that he is stepping down.

Sunak or Truss?

Truss has been a firm front-runner in the contest among Conservative Party members.

Truss and Sunak have come head-to-head at 12 campaign events over the last eight weeks to try to win over party members.

They have set out their views on the Bank of England’s mandate, tax cuts and the controversial plan to deport migrants to Rwanda, as well as the UK’s worsening cost-of-living crisis.

The result was chosen exclusively by members of the Conservative Party — that’s around 180,000 people by the most recent count who pay to be a member of the party, out of the 65 million people living in the UK.

The vote was carried out as a postal ballot which closed on September 2.

Next steps

Once the most popular candidate is announced, the formal process for appointing a prime minister begins.

It will include a trip to Balmoral Castle in Scotland for the official “kissing of hands” meeting with the queen, where the monarch asks for a new administration to be formed.

This is a break from tradition, as her 15th prime minister will be the first to not be officially appointed at the queen’s London home, Buckingham Palace.

The 96-year-old queen reportedly started experiencing “episodic mobility issues,” as announced by Buckingham Palace on May 9, which may explain the choice for the new prime minister to travel to her rather than making the 500-mile journey to London herself.

A ‘giveaway budget’ from the new PM?

The cost-of-living crisis will likely be top of the agenda for whoever will be moving into 10 Downing Street, as UK energy bills are set to rise by 80% in October and investors warn inflation could top 22% next year.

The next prime minister will be offering support for energy costs, predicted Alan Custis, head of U.K. equities at Lazard Asset Management, on CNBC’s “Squawk Box Europe” last week.

“As a prime minister you want to create a honeymoon period,” Custis said, “and there could be a general election.”

“Whichever candidate gets in, there’s potential for a giveaway budget as soon as they get in,” he said.
