The sister of a British man released from US detention after two years in says she has no idea how he will react when he returns to the UK on Tuesday.
Maxine Fiddler describes the past two years as 'a nightmare'
Maxine Fiddler's brother Jamal Udeen was one of five Britons suspected of terror links to be released from Guantanamo Bay.
Leaving behind four other British men in Cuba, the five are expected to land in the UK on Tuesday night.
Ms Fiddler said the past two years had been "a nightmare" for her family.
She had not received a letter from Mr Udeen, born Ronald Fiddler, for over a year and found it hard to imagine how he was coping.
Ms Fiddler, who lives in Manchester, told the BBC: "We really don't know what to expect, how he is, his state of mind, so I'm really scared about that.
"He may not want to speak to us, he may want to stay on his own, because can you imagine being locked up for two years - he'd be used to his own company.
"He may not want his family around him, it might be too much of a fuss, too much for him to take in."
She said she had no idea what she would say to her brother.
Ms Fiddler said: "I'm just going to put my hands around him and just thank God he is here.
BRITONS BEING RELEASED
Shafiq Rasul, 24, of Tipton, West Midlands
Asif Iqbal, 20, of Tipton
Ruhal Ahmed, 21, of Tipton
Jamal Al-Harith, 35, from Manchester
Tarek Dergoul, 24, from east London
"I can't say thank you to the US government, I've got nothing to thank them for because they've had him too long."
The past two years had "torn the family apart", and affected her father's health.
She said she was angry at the US Government and Prime Minister Tony Blair.
If she could meet Mr Blair, she would ask him why he did not use his influence with President Bush.
She said she would tell Mr Blair: "You have a lot of power, why didn't you use it?"
Home Secretary David Blunkett said anti-terror police would question the men on their return from Cuba.
But Ms Fiddler said she hoped her brother would not be subjected to further interrogation.
"What more do they think they're going to get from these people?" she said.
The release of Mr Udeen and the other four was secured after the US concluded they presented a low risk.
Mr Blunkett indicated four other UK detainees would probably face trial in the US as they had been picked up "in the combat zone" in Afghanistan.
The four remaining men are Feroz Abbasi, 23, Richard Belmar, 23, and Martin Mubanga, 29, all from London, plus Moazzam Begg, 36, from Birmingham.
