Britain's Foreign Minister Boris Johnson has officially renounced his U.S. citizenship, according to a list the Treasury Department released Wednesday.

Johnson, who was born in New York City, maintained a dual citizenship throughout his life, but had promised to renounce his American citizenship in 2015.

"An accident of birth ... has left me with this thing. I've got to find a way of sorting it out," Johnson said in February 2015, before initiating the formal process.

"The reason I'm thinking I probably will want to make a change is that my commitment is, and always has been, to Britain," the former London mayor explained at the time.

Johnson is one of the 5,411 people who renounced their citizenship in 2016, according to the U.S. Treasury Department. Johnson renounced his citizenship in the last quarter of 2016, according to the Treasury document released Wednesday.

Johnson has also been critical the U.S. tax system in the past, after he received a bill because of his citizenship. According to the BBC, Johnson settled the issue in January 2015, but called the law "absolutely outrageous."
