The mayoral election on 3 May comes at a critical time. Londoners are going through one of the toughest periods in recent memory. Despite this, there are signs of progress coming from the fresh and honest approach. The same fresh-thinking that has delivered the world's most successful bike hire scheme.

Boris's determination to end the waste and mismanagement of the previous mayor has freed up the money to pay for a strong plan for our future - helping to keep London the greatest city in the world.

Our campaign to get Boris re-elected is built on ordinary Londoners from across the city and we want to know what you love about your city.

So we're asking people to help us create a picture of the capital by submitting a photo of what sums up London to them. It could be something local - your favourite curry house, an interesting building on your local high street, a particular market stall you love - or one of our famous landmarks, but whatever you choose, be creative!

Submit your photos from today through to 20 March: www.backboris2012.com/enter. We'll be tweeting photos we receive, so make sure to follow us on @BackBoris2012.

The photographer whose picture is chosen as the best representation of London will win a personalised signed copy of Boris Johnson's Life of London and fully loaded BackBoris2012 goody bag, including a t-shirt, mug and much more.

And after 20 March, we'll be putting together a special feature using the photos we've received, so be sure to get yours in on time.

Despite the tough times we're going through, there is much to celebrate about London, so show us what London means to you!
