As previously reported, the Minister of Foreign Affairs, Liz Truss, will be the next prime minister of the United Kingdom after winning the most votes in the Conservative Party leadership contest, defeating the former Minister of Finance Rishi Sunak with 81,326 votes to 60,399 among party members. Truss will replace Boris Johnson, who resigned in July after a series of scandals.

Johnson formally resigns his post to the Queen on Tuesday, September 6. The new leader of the Conservative Party will be invited to form a government to the monarch at her Scottish residence Balmoral.

During her election campaign, Truss promised to be the "biggest friend" of Ukraine, following the example of Boris Johnson.
