More than £1000 has been raised to pay for the funeral of a homeless ex-soldier who died while sleeping rough on the streets.

Darren Greenfield, 47, who served with the Royal Tank Regiment in Bosnia, died in hospital last month.

The veteran struggled to adapt to life after leaving the army and became a familiar face outside Edinburgh's Waverley railway station.

The Ancre Somme Association Scotland has launched a campaign to raise £7000 for his funeral.

The organisation, which offers education, remembrance and supports Armed Forces charities, has collected £1120 so far.

Secretary Tommy Davidson said: "We heard Darren's sister on the radio saying the family didn't have the money to pay for the funeral.

"I felt that our association could do something to raise awareness of what Darren did for his country and the effects of PTSD.

"And alleviate some of the costs involved with his funeral."

Mr Greenfield's sister, Aston Robertson, said his experiences in the Balkans were his "downfall" and had left him suffering from post-traumatic stress disorder (PTSD).

"PTSD is very common in ex-servicemen," Mr Davidson said.

"A lot of people do not realise what it does to you mentally. Unless you've seen war or conflict, you won't fully understand.

"Unfortunately, Darren came back and didn't manage to get his life back on track."
