Liz Truss was expected to become the next prime minister of Britain on Tuesday. She arrived at Queen Elizabeth's estate in Scotland, Balmoral,

right after Boris Johnson gave his formal resignation to the monarch. During their meeting, the Queen will ask Truss, the leader of the Conservative Party,

o become Britain's future prime minister, as the country faces an extreme cost-of-living issue. Truss, who is 47 years old, takes office the day after 172,000 members of the ruling party chose her as their leader

This puts her in line to be named prime minister at a ceremony on Tuesday at the Queen's summer house. Truss is due to deliver her maiden address as the leader

of a nation of 67 million people apprehensive about rising energy costs and an impending winter of recession and labour unrest on Tuesday afternoon

After announcing his intention to resign in early July, Johnson lacked the authority to make key policy decisions

, so these issues have festered for the past two months.
