To ask the Secretary of State for Transport what proportion of his Department's overall procurement spend for each of the previous three financial years was (a) spent on joint procurement exercises with other Departments and (b) shared between different organisations within the same Department group.

The proportion of the Department's overall procurement spend for the previous financial year spent on joint procurement exercises with other Departments was 21%. The figures for the two previous financial years were not available within the time scale required to answer this question, but I will write to the hon. Lady in due course to provide this information, and place a copy of the letter in the Libraries of the House.

While there is collaboration within the departmental group on some procurement exercise, this is not material compared to the figures above.
