On July 20 (local time), Andy Burnham, leader of the UK's Labour Party, was sworn in as the new Prime Minister of the United Kingdom.

He becomes the new occupant of 10 Downing Street, succeeding former Prime Minister Starmer, who resigned after two years in office.

However, it was a cat that appeared at the venue before the new Prime Minister that drew the attention of the press.

[CNN Reporter: Larry, do you like Prime Minister Andy Burnham?]

Adopted in 2011 and living at the Prime Minister's residence for 15 years, Burnham is the seventh Prime Minister Larry has served.

Larry's official title, as introduced on the UK government website, is 'Chief Mouser to the Cabinet Office'.

Then-Prime Minister David Cameron brought Larry in from a cat shelter to tackle the infestation of mice at the residence.

However, Larry has shown remarkable talent in areas other than his primary duty of catching mice.

His greatest specialty is 'greeting guests'.

Whether it was a visit from U.S. President Trump, Ukrainian President Zelensky, or the late Japanese Prime Minister Shinzo Abe, Larry has always been at the door to welcome world leaders whenever they visited Downing Street.

He often steps out of the door before the Prime Minister to prepare the press for an interview, or is the first to greet the Prime Minister when they return home. He is the hidden power at 10 Downing Street, having faithfully assisted the Prime Minister from his closest side for 15 years.

Larry's food and care expenses are covered not by taxes, but by donations from the staff at 10 Downing Street.

This is because he is the symbol of 10 Downing Street, having steadfastly guarded the heart of British politics through the turbulence of seven different Prime Ministers over the past 15 years.
