Allegations from the United States that British spy agency GCHQ snooped on Donald Trump during his election campaign are "arrant nonsense", the deputy head of the U.S. National Security Agency (NSA) said in an interview on Saturday.
President Trump has stood by unproven claims that the Obama administration tapped his phones during the 2016 White House race. On Thursday his spokesman cited a media report that Britain's GCHQ was behind the surveillance.
Richard Ledgett, deputy director of the NSA, told BBC News the idea that Britain had a hand in spying on Trump was "just crazy".
