KEITH Green will be abseiling down Oxford’s John Radcliffe Hospital – dressed in a nappy.

Three years ago Mr Green, 47, and his partner Helen had identical twins, Oscar and Harry, at the JR, but they were born prematurely, and Harry died the next day.

Oscar was kept in special care for three months, and throughout that time the couple were helped by the children’s charity SSNAP, Support for Sick Newborns And their Parents.

Mr Green said: “They took care of my little one for three months, and I’m really grateful to them.”

He has raised £1,000 altogether for the SSNAP, and this year received a donation from PM David Cameron .

Mr Green’s abseil on Sunday, September 23, will begin at 12pm.
