Back from holiday and back into the hotseat for tonight’s sky dot com show.

First a plug for another web & news active exclusive. Next Monday, 28th April, Sky News is broadcasting a live debate between all the candidates in the election for London Mayor. The event takes place at 8pm and is due to last for an hour. Online however we are doing more. Before the main event I will be on-air with my guests looking ahead to the debate to follow – and then as soon as the gavel falls on the live debate, I’ll be back with the panel, the spin doctors from all sides and you – to give your verdict on how the candidates performed.

Your contributions will be important because you are the people that really matter – the voters with the power to choose their Mayor for the next few years! We welcome emails, blogs, and we’ll have the Skype kit with us too. Log on come Monday to see all the details.

And we’ll have a flavour of how the candidates are doing in tonights show. Nick Burcher is my guest. He’ll be comparing the online political campaigns in London and the USA.

We’ll have an update on the latest voting in the race for the Democratic nomination – and we’ll have the usual countdown of the top stories on the Sky News website today. Join us online or on TV at 7.30pm
