PMQs: Corbyn asks May about government Brexit documents

Jeremy Corbyn asks the prime minister about documents referred to by David Davis during a BBC Marr Show interview in June, adding that the Brexit secretary had now said "they actually don't exist".

Theresa May said MPs had asked for "58 sectoral impact assessments", but there was "over 800 pages of sectoral analyses" which has been made available to the Brexit select committee.
