Win a fantastic dinner cruise on the Thames

London Eye and County Hall are two of many iconic landmarks alongside the Thames. Photograph: Mike Matthews/Getty Images Writer Iain Sinclair's podcast on this website reveals the rich and varied history of London's most famous river. As well as a major highway for international trade, the Thames is an inspiration for artists and a place for hiding dark secrets. Now, you can trace London's colourful past for yourself by following Iain's route along the Thames. The Guardian has teamed up with Visit London to offer you the chance to win a leisurely evening cruise for two through the heart of London, from Westminster pier to the Thames Barrier and back again. There is no finer way to see London at night than from the river. When famous landmarks such as the Houses of Parliament and Tower Bridge are illuminated against the dark waters of the Thames, it offers a whole new perspective on the city. But this isn't just a chance to sightsee. You'll be on board the Showboat, run by City Cruises. During the three-and-a-half hour cruise you'll receive a welcome drink and a four-course meal with wine. There will also be live entertainment from a singer performing songs from West End shows and dancing to round off the evening. Along the way, you'll glide past some of the capital's most iconic sights, including the Merlin Entertainments London Eye, St Paul's Cathedral, the Millennium Dome and the Meridian laser at Greenwich. The prize also includes a one-night stay and buffet breakfast at the four-star Pestana Chelsea Bridge hotel on the south bank of the Thames, opposite Battersea Park. The flagship hotel of the Pestana Hotels and Resorts group, the Chelsea Bridge is well-placed for central London, being walking distance from Sloane Street and Victoria station.
