Prime Minister Boris Johnson 

Alexander Boris de Pfeffel Johnson is a British politician who has been the Prime Minister of the United Kingdom since 2019 and the head of the Conservative Party.

From 2016 to 2018, he was Secretary of State for Foreign and Commonwealth Affairs, and from 2008 to 2016, he was Mayor of London.

Boris Johnson siblings: Jo Johnson, Leo Johnson, Rachel Johnson

Boris and Rachel have four children: Boris, Jo, and Leo.

From his father’s subsequent marriage to Jennifer Kidd, the Prime Minister also has two half-siblings, Julia and Maximilian.

Boris Johnson’s younger brother, Joseph Edmund Johnson, is a former Government minister.

In the General Election in May 2010, he was elected MP for Orpington, and he was re-elected in 2015 and 2017.

Leo is far less well-known than his siblings.

He went to Oxford, which appears to be a Johnson tradition, but went on to enter politics.

Instead, he is a business owner and co-host of Radio 4’s Future-Proofing.

Max was born in 1985 in Brussels and is 22 years younger than Boris.

He, like his brothers, attended Oxford University before pursuing an MBA in China.

He eventually established his own investment firm, MJ Capital.
