Diary: Going underground for a lot to talk about

Fancy getting away from it all? Then Diary has the investment opportunity for you: a nuclear bunker with 360-degree views (from the top of the hatch, we assume) in Farmborough near Bath. This Cold War “nuclear observer post” and its accompanying 115 sq ft of subterranean accommodation is being marketed by Maggs and Allen. It comes with 1,367 sq ft of land, solar power and even its own postbox down the hill. Up for auction on 7 June, surely its guide price of £10,000 to £15,000 will be smashed – what portfolio could be complete without a nuclear bunker?
