It has been revealed by The Observer newspaper that the Conservative candidate for the Mayor of London is a member of the six Facebook groups mentioned by Deidre Brock. They are full of Islamophobia, antisemitism and the most disgraceful incitement to damaging property. The worst bit, for those of us who were in the House when our Members of Parliament were taken, are the death threats to the current Mayor of London, Mr Khan. Will the Prime Minister close down those Facebook pages, which were begun by Conservative members of staff, and will he investigate the role of the current candidate and her membership of those disgraceful racist Facebook groups?
