The father of UK Prime Minister Boris Johnson says he is applying for French citizenship now that Britain has severed ties with the European Union.

Stanley Johnson told France’s RTL radio he had always seen himself as French as his mother was born in France.

The 80-year-old former Conservative Member of the European Parliament voted Remain in the 2016 Brexit referendum.

His son Boris spearheaded the Leave campaign and later took the UK out of the EU as prime minister.

Stanley Johnson explained his reasons for seeking French citizenship in an interview broadcast on Thursday, hours before the UK was due to leave EU trading rules.

“It’s not about becoming French,” he told RTL. “It’s about reclaiming what I already have.”

He pointed out that his mother was born in France to a French mother. “I will always be European,” he added.

Stanley Johnson won a seat in the European Parliament when direct elections were first held in 1979, and later worked for the European Commission. As a result, Boris spent part of his childhood in Brussels.

Their brother, the Conservative MP Jo Johnson, resigned from the cabinet in 2018 to highlight his support for closer links with the EU.
