LONDON, Jan. 11 (Xinhua) -- The United Kingdom's (UK) economy is almost 140 billion British pounds (178.7 billion U.S. dollars), or 6 percent, smaller than it would have been because of Brexit, Mayor of London Sadiq Khan said on Thursday.
The country's departure from the European Union (EU) has also cost London's economy more than 30 billion pounds, Khan said during a speech in the City of London, quoting a report by Cambridge Econometrics commissioned by City Hall.
