To ask the Prime Minister

(1) whether he uses an Oyster Card in fulfilling his official responsibilities;

(2) whether the Oyster Card he was filmed with for television on 27 April is one he uses in fulfilling his official duties.

I travel making the most efficient and cost-effective arrangements. My travel arrangements are in accordance with the arrangements for official travel set out in Chapter 10 of the Ministerial Code, and the accompanying guidance document, "Travel by Ministers".
