(Reuters) - Eurosceptic British lawmaker Jacob Rees-Mogg said in an interview with CNBC he does not know if the 48-letter threshold has been reached to trigger no-confidence vote in Prime Minister Theresa May’s leadership.

British media, citing sources, reported minutes before Rees-Mogg’s interview that enough letters had been sent to the chairman of the Conservative lawmakers’ 1922 committee, Graham Brady, to trigger a vote of no confidence in May’s leadership.
