Gavin Patterson, BT CEO, will lead a host of celebrities including Bear Grylls, Helen Skelton and former Lion and England rugby world cup winner Ben Kay in the sponsored descent.
The event will launch a year of commemorations for the 350th anniversary of the Royal Marines as well as forming part of Sport Relief’s fundraising activities.
Money raised will be shared between the two causes.
The 620ft BT Tower has dominated the London skyline ever since it opened in 1965 and remains fully operational, supporting UK and global broadcasters including ITV, Channel 4, BSkyB and CNBC Europe.
Gavin Patterson, CEO BT said: “I’m delighted that BT Tower is hosting this event, particularly as it is a momentous year for the Royal Marines.
“Given that I’m not the greatest fan of heights, this is going to be a mental challenge as well as a physical one for me. I’m concentrating on the two terrific charities that will benefit from our fundraising and the fact that all the money donated via MyDonate will go directly to them.”
All abseilers have been trained by the Royal Marines who will supervise the event.
Major General Ed Davis CBE, Commandant General Royal Marines said: “I’m delighted that the Royal Marines are supporting BT on this abseil at the start of our 350th anniversary year.
“It promises to be a great day for everyone taking part, including my own Royal Marines Corps family, where we hope to raise a vast amount of money for Sport Relief and the Royal Marines Charitable Trust Fund – two charities that really do make a difference to the quality of life of people in need and inspiring young people to achieve their potential.”
