The couple's two children were at the ceremony
Former Mayor of London Ken Livingstone got married at London Zoo on Saturday - but still presented his radio show in the morning.
Mr Livingstone, a renowned newt lover, wed long-term partner Emma Beal in the Mappin Pavilion, near the Reptile House in the zoo by Regent's Park.
The former mayor, 64, insisted the location had been chosen to stop children at the ceremony getting bored.
He hosted his show on London's LBC Radio to "get out of the way".
"I think there isn't much of a role for the groom in the morning," explained Mr Livingstone.
"If I'd stayed at home, I'd be offering unhelpful advice about the better way of doing something and winding everybody up, so I just thought I'd come into work."
Two of Mr Livingstone's five children are with Ms Beal, who was once employed as his administration manager.
The politician said they were "very excited", adding: "Most kids don't get to go their parents' wedding."
But one figure who was not invited was current London mayor Boris Johnson, who famously dubbed his rival in the 2008 elections the "Newt King".
Mr Livingstone said: "Oddly enough, it is a small family wedding and I know he's related to the Royal Family - I hope he's not related to me!"
