Boris Johnson and his team (let's not pretend it was just him) have finally handed the password to the @MayorofLondon Twitter account to Sadiq Khan and his crew, marking the end of an era. No more twitter pics of Boris's blonde mop popping up around the capital, no more sassy replies to #AskBoris questions.
Khan's squinting face has replaced Johnson's profile picture and banner photo.
All of Johnson's old tweets remain, although they now appear with Khan's face next to them. Which, as you might imagine, has some quite awkward consequences. Here are a few notably LOL-worthy tweets, with Khan's face next to them.
