[holding answer 17 September 2008]: The UK Border Agency achieves this by excluding those who have participated in terrorism from asylum under article 1F of the UN Convention Relating to the Status of Refugees. The statistics relating to exclusion from the 1951 Convention under article 1F do not differentiate between those who are refused asylum on grounds of participation in terrorism or for other grounds which are covered within article 1F. It is therefore not possible to give a precise figure in answer to the hon. Gentleman’s question, except at disproportionate cost.
