Homeless people will get a waterproof map of where to eat, sleep, get clean and stay warm thanks to a Secret Millionaire.

The map is produced using a £25,000 donation from Bradley Reback, who went undercover as an unemployed homeless man in Brighton and Hove for the Channel 4 show.

It was part of £70,000 he donated to city charities after working as a volunteer and seeing first-hand the challenges they face supporting the most vulnerable people in the area.

His adventures living in a van and surviving on Jobseeker’s Allowance were shown last night.

The Argus revealed that Mr Reback had been filmed in the city earlier this month, but this is the first time it has been revealed how much he donated.

At Brighton Unemployed Centre Families Project, he became a volunteer before revealing his identity and handing over £25,000.

Part of the money is being used to fund a map for rough sleepers, showing hostels, soup kitchens, day centres and sources of advice.

Since then, former University of Sussex student Mr Reback has returned to help see the idea through.

Mr Reback also made a £25,000 donation to the Safe and Sorted youth centre in Barcombe Road, Moulsecoomb.

The project gives advice to up to 900 young people a year on housing, jobseeking, sexual health and addiction.

Its manager, Niki Eldridge, said the money ensured the charity did not go under.

Mr Reback gave £7,500 to the Moulsecoomb Forest Garden and Wildlife Project after carrying out volunteer work including roof thatching.

The charity works with young people who have had problems at school, helping them develop by teaching them skills like gardening and carpentry.

Another £12,500 went to the Towner Club, which supports people suffering from dementia who are under 65.

Mr Reback said he intends to stay involved with all of the groups.
