Human
rights groups also said that any plans for immediate deportations
would be legally challenged.
Under
the 1971 Immigration Act, the home secretary has the power to deport
foreigners he believes pose a threat to national security.
But
international law prevents London from deporting people to countries
where they face inhumane treatment.
Earlier
this month, Britain signed an agreement with Jordan which London says
will protect deportees from ill-treatment.
Britain
is also seeking similar accords with countries such as Algeria ,
Lebanon and others.
Meeting
In
a separate-related development, Birmingham Muslims were to meet later
Thursday with Home Office Ministers to debate tackling extremism and
reforming mosques, the Birmingham Evening Mail reported.
UK
Ministers have set up a series of meetings with Muslims to discuss
issues raised by the London bombings on July 7, before new laws are
unveiled by Clarke next month.
Home
Office Minister Paul Goggins will attend the meeting, which follows
others in Oldham, Burnley, Leicester, Bradford, Manchester and Leeds.
Members
of other religions, including Anglicans, will also take part in the
summit, which will look at improving relations between different
sections of the minority.
The
meeting will discuss the effect of the terror attacks on Asians who
are not Muslim but have experienced hostility as a result.
"Issues
which people have raised in the previous summits included disaffection
among young people, and not just Muslims but young people in
general," a Home Office spokeswoman told the paper.
"We
also looked at whether there should be some kind of controls on imams,
and a requirement to speak English."
One
MP, however, warned she feared the government was failing to hear the
voices of all Muslims.
"You
need to be very careful when you invite community leaders that you are
not just inviting the people who put themselves forward, and may not
represent the community as a whole," Gisela Stuart (Lab
Edgbaston) said.
Britain
's Muslim population is estimated at 1.6million, with 1.1million over
18, meaning more than half a million may have considered the
possibility of leaving, said the Guardian.
