UK embassies blacklist radicals

Mr Clarke promised to exclude radicals after the 7 July bombings.

British embassies have come up with a list of up to 100 radicals who would not be welcome in the UK, the home secretary has confirmed.

After the 7 July bombings, Mr Clarke told parliament he would exclude people from the UK for actions such as inciting and encouraging terrorism.

He told BBC2's Newsnight that British high commissions were also asked for nationals who may meet these criteria.

Those on the list, seeking to enter the UK, will be reviewed by a minister.

Warning index

Mr Clarke stressed that no foreign government had been approached to supply names of individuals it considered undesirable.

Between 50 and 100 names were put forward for inclusion on a "warning index".

"They have sent names, we are considering them, and they are currently on our warnings index which means there would be a ministerial decision on any individual case," Mr Clarke told Newsnight.

He said: "What we did do was ask our missions in countries throughout the world to think whether there were any individuals who might be refused permission to come into this country - I'm talking about foreign nationals - on the grounds that their presence here was not conducive to the public good in accordance with the unacceptable behaviours that I described.

He added: "The total number that we're talking about is in the order of 50 to 100 and they're being looked at - at this moment - but there are people we are considering adding to the warnings index on the criteria I set out, quite publicly, to Parliament and set out in a very clear way."
