Tory Conference: Johnson jokes about being MP and mayor
Boris Johnson recalled welcoming the former French prime minister Alain Juppé when he visited London, and noted how he was a mayor and PM at the same time.
He told the conference that it was the "kind of thing they do in France, a very good idea in my view", before shouting "joke" several times, as the delegates laughed.
Mr Johnson has been linked to a return to Parliament - and potential future Conservative leader and prime minister - possibly while still mayor of London.
