"The reason I'm thinking I probably will want to make a change is that my commitment is, and always has been, to Britain," Johnson told The Sunday Times during his tour of the eastern United States last week. He noted that his American citizenship was "an accident of birth that has left me with this thing. I've got to find a way of sorting it out."
While British legal experts have stated that it would be perfectly legal for Johnson, who was born in Manhattan in 1964, to hold offices up to and including that of the Prime Minister as a dual citizen, it could lead to questions from voters about where his loyalties lie.
Johnson's aides have noted that dual taxation was another issue of concern for the mayor; in January, he was forced to pay a large capital gains tax to US tax authorities after selling his home in north London. Johnson described the tax as "absolutely outrageous."
Johnson told The Times that he would approach US Ambassador to Britain Matthew Barzun to formally make the request in the near future. "It is a laborious business. They don't make it easy for you," he noted.
According to CNN using data provided by the Inland Revenue Service, Boris is part of a growing trend or US Citizens renouncing their passport. Experts speculate that the majority of citizens giving up their US citizenship are doing so for tax reasons.
Johnson will not run in the 2016 London mayoral election; he is instead running for parliament for the Uxbridge and South Ruislip constituency in western Greater London in May's parliamentary elections. Last week, Johnson told reporters that he had no intention of challenging Mr. Cameron for the Tory leadership any time soon.
