From 9-10pm on my LBC Show tonight I will be hosting the first radio debate between Labour's London mayoral aspirants, Ken Livingstone and Oona King. They'll be debating each other on their visions for London and how they intend to oust Boris Johnson from his job in May 2012.
If you've got any questions you think ought to be put to the two of them feel free to leave them here, or you can text 84850, email iain AT lbc DOT co DOT uk during the course of the day. We'll also be taking questions on the telephone on 0845 60 60 973 from 7pm.
The show starts at 7.15pm and you can listen on 97.3FM in London and surrounding areas, on digital radio all over the country, on Sky channel 0124, Virgin 973 or stream the programme at www.lbc.co.uk.
