Tory mayoral candidate Zac Goldsmith came unstuck when quizzed on London trivia on Tuesday - but how much better can you do?
Poor old Goldsmith was left rather nonplussed when Norman Smith asked him some questions about the city he hopes to represent.
The Richmond Park MP, who is hoping to succeed Boris Johnson as London Mayor on May 5, came unstuck when asked which team played its football at Loftus Road.
He also bombed when quizzed on which tube station comes after Tottenham Court Road when travelling east on the Central Line.
The answers are of course Queens Park Rangers and Holborn.
Sadiq Khan's performance on a similar quiz was rather more heartening, with his knowledge of EastEnders, football, museums and the Tube proving strong.
We've put together some of our own questions about London, so you can find out if your knowledge matches that of a mayoral candidate...
