British Foreign Secretary Liz Truss will replace Boris Johnson as the British prime minister after the UK's Conservative Party voted to make her the leader of the government. She beat out former Finance Minister Rishi Sunak and is expected to be formally named prime minister by the Queen on Tuesday.

As the British foreign secretary, Truss has delivered some of the most hawkish rhetoric against Russia in NATO's response to the invasion of Ukraine. When the war first broke out, Truss said that she supported individuals from the UK who wanted to fight in Ukraine.

While campaigning to become the prime minister, Truss said if she took the position, she would follow in Johnson's footsteps and be Ukraine's "greatest friend" to ensure that Russian President Vladimir Putin "fails in Ukraine and suffers a strategic defeat."
