A number of Britons detained in Israel after soldiers stormed an aid convoy they were part of are due to return to the UK, the Foreign Office has said.
A spokesman said "several" of the 41 Britons held had agreed to be deported and it would "seek clarification" on the fate of those who had not.
Deputy Prime Minister Nick Clegg has questioned whether it was in Israel's interest to "confine" so many people.
Activist Hasan Nowarah, from Glasgow, has already been returned to the UK.
The Foreign Office says it understands any Britons who do not agree to be deported will be forcibly returned.
Nine activists died when Israeli commandos boarded the six-ship convoy on Monday, prompting increased international pressure on Israel to lift its blockade of the Gaza Strip.
