Johnson: Data Communications is 'resignation issue'

Former Home Secretary Alan Johnson has said a proposed Data Communications Bill should be a "resignation issue" for Theresa May.

Johnson, speaking on the Andrew Marr Show, said the bill should be on the statute book before the next election.

"The security services... need to know who's been contacting who", he told Nick Robinson.
