An armour-plated bus believed to have been used by Margaret Thatcher has sold for nearly £17,000.
The 28-tonne "battle bus" is thought to have been built in the 1980s for the former prime minister's Northern Ireland tour.
The estimate had been £10,000, and went to a vehicle collector at an auction in Northamptonshire.
The bus has a blast-proof floor and armour-plated glass as well as a bomb-proof armour-plated body.
It was thought to be safe from chemical, biological and nuclear attacks.
