In her speech in the Italian city of Florence on September 22, May outlined a transition period of around two years of trading on the same terms, but no payments for single market access.
Mrs May told BBC 1's Andrew Marr Show: "Boris is absolutely behind the Florence speech and the line that we have taken".

When Sky News asked if he would support Mrs May in 2022, he replied: "Yes, if that's what she wants to do she should, and she'd have my backing".
