Sir Sir Richard Branson, Lisa Snowdon, Dermot O'Leary, Sir Steve Redgrave, Sir Ben Ainslie, Dave Berry and Fern Britton are among supporters of the Royal National Lifeboat Institution's (RNLI) forthcoming Mayday campaign, May 1-4.

The stars appear in photos shot by RNLI volunteer crew member and professional photographer Nigel Millard, each wearing a pair of bright yellow wellies, as worn by the charity's volunteer lifeboat crew members. Branson commented 'I'm wearing yellow wellies to show my support for the RNLI. I have a huge amount of respect for their volunteer lifeboat crews. Whatever the weather, they're prepared to head out to sea and put their own lives in danger to save others. If you can, please donate to the RNLI this Mayday'.
