Shaker Aamer is expected to return to the UK within days, the Mail understands.
The last British resident in Guantanamo Bay is due to leave the infamous camp later this week or early next according to sources in the UK and US.
One Whitehall source said: ‘He will be out within days. We’re working on the practical details of how it will happen.’
A senior State Department official said: ‘Shaker is coming home and it will be in the near term.
‘The delay past the 30-day mark is due to logistical arrangements.
‘We cannot release the exact date he will be released due to security concerns. Shaker will be coming home’.
Father-of-four Mr Aamer has been detained at the US military jail in Cuba since 2002.
He was cleared for release at the end of last month, but Mr Aamer’s wife Zin and four children – one of whom he has never met - are still waiting for his return.
Yesterday it was claimed Mr Aamer’s release was delayed to appease US politicians visiting the camp. Three Republican Senators visited the camp on a ‘fact-finding’ mission.
Mr Aamer, 46, says he was working as a charity worker in Afghanistan when he was kidnapped and handed over to US forces in 2001. He says he has been tortured during his time at Guantanamo.
