Gordon Brown has called the election.

He, David Cameron, Nick Clegg and hundreds of candidates will soon be courting your vote. But the truth is they're asking you to send them to a broken Parliament.

And, worse, the majority of them are still defending our broken political system, which has so obviously failed its purpose and its people.

But there are some who understand the real and urgent need for change.

POWER2010 have set up a simple tool on their website that allows you to email all of the candidates in your local area and find out which camp they fall into: do they want real change, or more of the same?

Sending a message will only take a minute or two and you can get started here.

This year POWER2010 ran the UK's largest-ever democratic consultation. Over 40,000 people have been involved - over 100,000 votes have been cast. And all of it was building to this moment.

We need to send a deafening message to every candidate in the UK that we want real change at this election, not more of the same.

We can only do this with your help and support. We are at a crossroads. The election campaign will be over within weeks - and we all need to do everything that we can to make sure Britain doesn't go back to politics as usual on 7 May.

I am writing to my candidates in Oxford West and Abingdon and asking them to sign the POWER Pledge to show they are committed to cleaning up and reforming our politics.

I'd like you to do the same - please click here to contact your local candidates.
