A man with Down's syndrome faces deportation to Lebanon after his application to stay in the UK was refused by the Home Office.
Wadih Chourey, 44, came to the UK from Lebanon in 1997 and his parents, who lived in Beirut, died in 2010.
Mr Chourey is supported by his two brothers, Camil and Joseph, who have never relied on public funds, and has nobody in Lebanon willing or able to care for him.
He was originally brought to the UK after being mentally and physically abused outside his parents’ home.
Mr Chourey, who lives in Vivienne Close, East Twickenham, initially had his application to remain in the UK refused, but was successful in an appeal earlier this year.
The judge ruled under article eight of the Human Rights Act that it would be a "disproportionate interference" to his right to a private and family life to insist he returned to Lebanon.
But the Home Office appealed the judge’s decision and the Chourey family is now fighting against the appeal.
In a letter to James Brokenshire, minister of state for security and immigration, Vince Cable, MP for Twickenham, said: "This is a disgraceful position. This is a man who cannot cook for himself, who cannot operate a washing machine or use a computer.
"His welfare is completely dependent on his brothers, who clearly provide a loving and caring home for him yet Home Office lawyers suggest there is nothing compelling or exceptional about the case and assume that Mr Chourey could seamlessly reintegrate into Lebanese life as if he never left."
Members of the Old Isleworth Four Roads Residents’ Association are among those fighting to help Mr Chourey stay in the UK.
Colin Marsh, chairman of the group, said: "Wadih and Camil are very much part of our community and Camil and his brother Joseph are both respected and admired for their love and care of their brother Wadih.
"If he is forced to return Beirut, it is unlikely he will survive as he is unable to care for himself as, due to his mental disability, he is naive, childlike and innocent."
Dr Cable said he would appeal the Home Office's decision on humanitarian grounds and will seek to get an appointment with the minister for immigration to discuss the case fully in the coming weeks.
A Home Office spokesman said: “He has appealed the decision so it would in inappropriate to comment while legal proceedings are ongoing.”
