So boris Johnson was obliged to pay cap gain taxes after selling his house? LOL.
Boris Johnson
The former foreign secretary relinquished his US citizenship in 2016. He was born in New York to British parents. All children born in the US are automatically US citizens. In 2013 he called the US taxation system "absolutely outrageous" when US tax authorities demanded he pay capital gains tax on the sale of his north London home.
