"As a result, the boy’s educational needs were not met throughout his last three years at secondary school," the ombudsman spokesman added.

The ombudsman has recommended the Council pay Adam’s mum Denise Miller, £1,000 compensation, and that they set up a £20,000 fund for Adam’s future and pay three years’ college fees.

Speaking exclusively to the Stockport Express, Denise spoke of her six-year fight to get suitable schooling for Adam, now 17.

"It’s been a very, very hard struggle," she said. "I have lost a business I have had for 20 years. It’s very upsetting - I feel that it’s placed the family under so much pressure and stress and I think they have been so unfair in the way they have handled everything."

Adam was moved to Reddish Vale in 2002 after thriving at specialist primary Oak Grove, in Cheadle Heath.

"I could tell in the first six months of him being in mainstream school that it was going wrong," said Denise. "They were phoning up and telling me things that were happening, but they were just treating him as a naughty child."

When Denise complained, the Council tried Adam on two work placements - one of which, she claims, was with young offenders, despite requests for good role models.

"Socially it had a very bad effect," she said. By Year 10, Adam was only being allowed into school one day a week, missing out on vital social skills and, claims Denise, making his disorder even worse.

But despite the fact Reddish Vale couldn’t cope, the Council ignored requests for him to be transferred to a specialist independent school.

A Stockport Council spokesman said: "This young person has clearly been let down by the Council and we are sorry for our failings.

"We will ensure theperson is supported in the future."

Despite his problems, Adam still managed to gain two GCSEs. But Denise has now lost her 20-year-old art business after spending so much time at home looking after him.

"If Adam had been left any longer he could have ended up in prison," she said. "Now I’m left to pick up the pieces."
