Under the Ministerial Code Departments are expected to make efficient and cost-effective travel arrangements, taking due account of security considerations in accordance with the rules set out in Travel by Ministers. The Secretary of State for Defence has travelled overseas by rail on two occasions; the first was for a return journey between London and Brussels. The second trip involved a journey from London to Brussels, an interconnecting rail journey between Brussels and Paris before returning to London from Paris. Domestic rail services have been used for a single journey from London to Plymouth, a return journey between London and Colchester, and a single journey from Inverness to Edinburgh.
The Secretary of State has made no journeys on the London Underground, tram or light railway services or buses in connection with his ministerial duties.
