Wes Streeting warns Britain has just over 1,000 days to get ready for war before Russia could strike in 2030

Streeting called readiness for conflict his 'defining priority' and 'the only metric that counts'. Households are already being told to stockpile up to nine litres of water and three days of food under the 'Be Ready' campaign. Prime Minister Andy Burnham has backed the advice. Yet Labour has still not set out how it will hit John Healey's target of 3% of GDP on defence by 2030.

Streeting says he is '100 per cent' confident of meeting Nato's 3.5% target by 2035.

He blamed the Tories for leaving Britain the smallest army since the Napoleonic Wars.

Britons are also told to keep cash, blankets, a torch and a wind-up radio at home.
