Support – former British prime minister (5)

I believe the answer is:

truss

(Other definitions for truss that I've seen before include "Hay bundle; tomato cluster" , "Bundle of hay or straw" , "Padded device worn to support a hernia" , "Surgical support" , "Support for body" .)

I've seen this clue in The Guardian.
