Robert Cook, a Stagecoach bus driver in East Cambridgeshire, will sleep outside for one night to raise money for homeless veterans.
Robert, who is a former Service Veteran with the Coldstream Guards, will be sleeping outside as part of 'The Great Tommy Sleep Out' campaign, which is ran by the Royal British Legion.
The bus driver is hoping to raise money and awareness of the fact that around 6,000 veterans are experiencing homelessness in the UK.
Robert said: "Nobody would say that the challenge exactly replicates the experience of sleeping rough, but it is still a challenge to do.
"I feel so strongly about the fate of so many people who have given their all to serve and protect our country, and who are now facing the consequences of that decision.
"It is easy to become disillusioned and think that nothing can be done to help these veterans, but we can all do our bit, so it is good to make a positive step to help out."

Darren Roe, Managing Director of Stagecoach East, said that everyone is "very proud of Robert for taking on this challenge".
