BBC NEWS | UK | Nuclear threat sparked tea worry

The threat of a nuclear attack on the UK in the 1950s caused concern over the supply of tea, top-secret documents which have now been released reveal.

Government officials planning food supplies said the tea situation would be “very serious” after a nuclear war.

“It would be wrong to consider that even 1oz per head per week could be ensured,” they stated.

The papers were released under the Freedom of Information Act by the National Archives at Kew.
