I think it is time for Mr Marr to retire. He seems to think that his show is for the viewers to hear his opinions on everything rather than interview the people for their views.
Mr Marr may not personally like or approve of Mr. Johnson but respect is due as he is our prime minister. It would have been good to let Mr Johnson finish his sentences without interrupting or talking over him as I was interested to hear Mr Johnson, not Andrew Marr.
Later in in the programme he interviewed the shadow education secretary with little or no interuption in spite of the trite rubbish she was speaking. Mr Marr is so very obviously biased he does not produce a good interview. He is so grumpy I wonder how anyone agrees to be on his show.
