Since the Routemaster was launched nearly 50 years ago red double deckers have become synonymous with London.

And while they are unlikely to change colour they are due a makeover for the 21st Century, having almost entirely been withdrawn from service in the capital, except for two heritage routes - nine and 15.

Mayor of London Boris Johnson pledged in his election manifesto to replace the controversial bendy buses and update the much-loved bus and launched a public design competition.

The change could now be partly inspired by Kilburn's Frances Faulder design which has earned her £1,000.

The money was given to Miss Faulder after she entered a worldwide competition started by Mr Johnson to help pick a look for the new buses.

And while her idea did not quite earn her the top prize of £25,000 in the design section of the contest, hers was voted the most imaginative.

The 24-year-old graphic designer was among more than 700 people to enter the competition after it was opened in July last year.

Mr Johnson said: "When I launched this competition, I asked for stylish and imaginative designs which would resonate with Londoners.

"We have had a phenomenal response, with ideas submitted from around the globe and I know that, like me, Londoners will be waiting eagerly to see how these ideas evolve into the final design that will appear on our roads."

Transport for London are expected to make a final decision on the new look within 12 months, and the prototypes should be on the streets of London by 2011.
