More than a quarter of Britons prefer to take breakfast in the nude.

To celebrate the fact, and the start of organic food fortnight, a number of hardy souls braved the violent storms lashing the UK and dined al fresco next to the River Thames in London this morning in their birthday suits.

Organic food fortnight, organised by the Soil Association, runs from Monday until September 21.

During the period individuals, businesses and community groups will be hosting events to promote the benefits of organic food and production.
