Over £1,000 has been raised for the funeral of a homeless former serviceman who tragically died while living rough on the streets. 

Darren Greenfield, 47, served with the Royal Tank Regiment in Bosnia during conflict in the 1990s but tragically 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. 

Now the Ancre Somme Association Scotland has launched a campaign to raise £7,000 to give Darren the send-off he deserves. 

The organisation, which offers education, remembrance and supports Armed Forces charities, has collected £990 from generous members of the public so far.

Tommy Davidson, secretary of the association, 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." 

Darren's sister, Aston Robertson, said the experience in the Balkans was Darren's "downfall." 

She said it left the former private school pupil with post-traumatic stress disorder (PTSD). 

Darren also spent time with the Royal Army Pay Corps and Adjutant General's Corps.

Mr Davison said he wants to make sure Darren is not forgotten. 

"It's disgusting that people who have served their country can even be in a position such as Darren's", he said. 

"We just want to do our best for Darren and his family. 

"He deserves to be honoured and remembered for sacrificing his life for us all. 

"Now it is our turn to give something back." 

Friends have left floral tributes at the entrance to the steps of Waverley station, describing Mr Greenfield as "good as gold". 

Speaking to BBC Scotland's Stephen Jardine programme, Aston described Darren as her "hero", adding that he received no help after leaving the forces.

She said: "I feel the damage was already done, if he had got help in the beginning, it would have been a lot better." 

Mr Davidson added: "PTSD is very common in ex-servicemen. 

"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. 

"I left the forces 20 years ago and I was left to my own devices to find a job and fit back into life back home."
