It appears the Oliver Letwin's mind has boggled upon discovering that the cost of a Zebra-crossing is £114,000. Personally it doesn't surprise me one bit, but then I read Hansard so much these days that insane figures for things that should not cost as much as they do is par for the course.
Apparently the Zebra-crossing cost is "made up of £11,000 for designing each crossing, despite their apparent similarity, £16,000 for the equipment and £87,000 for the labour". The breakdown of figures certainly reinforces a truism. It's always labour that stings you!
