Five of the nine British nationals being held by the American authorities at Guantanamo Bay detention camp are being released after more than two years in US military base in Guantanamo Bay.
They may face questioning by British police when they arrive in the UK.
US authorities have not brought charges against any of the Britons but two of the four detainees who will remain in Camp Delta, Feroz Abbasi and Moazzam Begg, are said to be candidates for "potential proceedings".
Asif Iqbal, 20, from Tipton, West Midlands
He was picked up by US special forces in Afghanistan. As a child he studied at the Sacred Heart school and the Alexandra High School in Tipton alongside Shafiq Rasul and Ruhal Ahmed.
He left school at age 16 to work in a factory.
Unconfirmed reports suggest he was detained in northern Afghanistan by the Taliban's enemy, the Northern Alliance.
It was at his family's suggestion that Asif went to Pakistan, and his father,
Mohammed, accompanied him; his parents believed it was time for him to get
married and settle down.
Mr Iqbal met his prospective bride during his first week in Faisalabad, but told
his father he wanted some time to think and went to Karachi, but did not return,
according to reports.
Shafiq Rasul, 24, from Tipton
Reportedly captured by US forces in Afghanistan.
He studied alongside Asif Iqbal at the Alexandra High School and Sixth Form Centre and they lived streets away from each other in Tipton. His family describe him as shy and "westernised".
He travelled to Pakistan in October 2001, apparently for a computer course, and his family lost contact with him in December.
He had only been abroad before for trips to Benidorm and Tenerife on an 18-30 holiday. He was a passionate Liverpool FC fan, was into fashion and clubbing, according to his family.
Mr Rasul is believed to have been captured in Mazar-e-Sharif, Afghanistan.

Jamal Udeen / Harith, 35, from Manchester

He was believed to have been captured by US forces while being held in Kandahar
Jail. He had been away from home only three weeks when he was captured.
According to reports, he told US soldiers he had paid a lorry driver to take
him from northern Pakistan to Iran as part of a backpacking trip, but was
stopped near the Afghan border by Taleban soldiers who saw his British passport
and jailed him, fearing he was a spy.
Born Ronald Fiddler to devout churchgoing Jamaican parents, Udeen converted to Islam in his 20s.
His family say he is a gentle, quiet man who rarely spoke of his faith unless
asked, and after four years learning Arabic and teaching English at Khartoum
University in Sudan, seemed happy enough to return home, marrying and setting up
a computer business with his wife.
He was a devoted father to their three children and was devastated when the
marriage broke down, moving back to Manchester, where he worked as an
administrator in a Muslim school.
