Please could you provide the following information:
1) the total annual spend on all large national infrastructure projects in the U.K. per year since 2016.
2) a breakdown of the total annual spend per year by the categories as stated in the National Infrastructure Delivery Plan 2016 -2021: roads; rail; international gateways; energy; communications; flood defence; water; science & research; housing & regeneration; local transport.

I look forward to receiving the information within 20 working days.

Yours faithfully,
