To ask the Secretary of State for the Home Department what the cost of provision of security cover for ex-Ministers was in each of the last five years; and what the highest cost relating to any one ex-Minister since his or her retirement was. 
§ Mr. Blunkett
We seek to ensure the most effective and efficient protective security arrangements for public figures in the light of the changing threat from terrorism and other continuing risks. It is not our policy to comment on the details of protection arrangements for individuals, as to do so could compromise their security.
An exercise has obviously been conducted in rearranging the particular level of threat to those no longer in post and arrangements have been made where this is judged to be appropriate based on the security threat to the individual concerned.
