Sadiq Khan has revealed he has found it “difficult to switch off” since beginning London’s top job 100 days ago.
The Mayor admitted he has the capital on his mind “all of the time” and that the role was “all consuming”.
“The problem with working all hours is that sometimes you can drop the ball,” he said.
But he said wife Saadiya and their two teenage daughters understood because they “know what we signed up for”.
Mr Khan said the highlights of his first 100 days in office included appointing more women to senior roles at City Hall, and that he was “really proud” of publishing the first gender pay audit.
The Mayor has also published plans to tackle air quality, boosted neighbourhood policing and started building his Homes for Londoners team.
He admitted the biggest disappointment of his mayoralty so far had been the result of the Brexit vote.
“That was the low point for me.
"But what is important is that even though we may well leave the European Union, I’m quite clear that doesn’t mean leaving the single market,” he said, adding that London, which voted Remain, must have a voice in the negotiations.
