UK Foreign Secretary Liz Truss is expected to beat Rishi Sunak and be announced as the new leader of the Conservative Party and the country’s next Prime Minister.

Her rival is former Finance Minister Rishi Sunak, who quit Boris Johnson’s government in July.

The winner of the leadership contest will be announced in under an hour at the Queen Elizabeth II Centre, near the Houses of Parliament, by Chairman of the 1922 Committee of Conservative backbench MPs, Sir Graham Brady.

Either Truss or Sunak will formally take over as Prime Pinister on Tuesday, after months of scandals plunged Johnson’s administration into crisis and forced him to resign.

The contest began in mid-July, when Johnson was forced out by a ministerial revolt over a string of scandals.

In a break with tradition, the winner will travel to Balmoral Castle in Scotland to be appointed by the Queen, rather than at Buckingham Palace.

Britain’s new leader will inherit a cost-of-living crisis, the aftershocks of Brexit and a war in Europe.

The Conservatives are losing support in opinion polls after 12 years in power.
