Johnson, a former member of the European Parliament, told French radio RTL that he “will always be European” in an interview broadcast on Thursday.
“It is not a question of becoming French. If I understand correctly, I am French,” he told RTL in French, highlighting his family’s connection to the country.
“My mother was born in France, her mother was entirely French, as was her grandfather. So, for me, it is a question of recovering what I already have,” he said of the decision to become a French citizen. “So, I’m very happy.”
Britain officially leaves the EU’s single market and customs union when the transition period ends at 23:00 GMT (18:00 ET) on New Year’s Eve.
Stanley Johnson insisted that Brexit will not mark the end of European identity for him or the English people. “I will always be European, that’s for sure. You can’t say to the English, ‘You are not a European,'” Johnson told RTL.
“Europe is always more than the common market, it is more than the European Union”, he added. “But that said, yes, having that link with the European Union is important.”
