An iron bus believed to have been used by Margaret Thatcher is to go under the hammer later today in Northamptonshire, according to auctioneers.
The 28-tonne bus is thought to have been built in the 1980s for the former prime minister's tour of Northern Ireland.
With just over 17,000 miles on the clock, it's expected to reach a price somewhere in the region of £10,000 - £12,000.
It has a Foden chassis, body by Glover and Webb and is powered by a 12-litre Rolls-Royce engine.

This isn't a good-looking vehicle by any stretch of the imagination - but is of social and historical interest. It is an irreplaceable one-off, an iron bus for the 'Iron Lady'.
