It would incur disproportionate cost to collate the information requested by the hon. Member as this information is not held centrally in the Foreign and Commonwealth Office.
The Government have published on an annual basis a list of all overseas visits by Cabinet Ministers costing in excess of £500, as well as the total cost of all ministerial travel overseas. The Government’s annual publication about overseas travel by Cabinet Ministers is accessible at:
http://www.cabinetoffice.gov.uk/propriety_and_ethics/ministers.aspx
The list includes details about the number of officials accompanying a Minister when non-scheduled travel is used for the trip. Copies of lists covering information going back to the 1997-98 financial year are also available in the Library of the House.
All official travel is undertaken in accordance with the ‘Civil Service Management Code and the Ministerial Code.’
