More than one million Britons using food banks, says a report by the Trussell Trust

More than one million British people are reliant on food banks, according to figures from the Trussell Trust, the UK's biggest provider of emergency food aid.

The report by the trust which has more than 400 food banks in Britain comes as the Labour Party aim to attack Conservative leader David Cameron over food poverty. According to the Independent newspaper, the party will accuse him of being out of touch.

The official figures, released on 17 April, showed the number of people given three days' emergency food by the Trussell Trust rose from 2,814 in the 2005-06 financial year to 61,468 in 2010-11, 346,992 in 2012-13 before jumping sharply to 913,138 in 2013-14 – including 582,933 adults and 330,205 children.

In a letter to the Prime Minister, seen by the Independent, Rachel Reeves, the shadow Work and Pensions Secretary, said the 618% rise in the number receiving emergency food aid from the trust in the past three years was "shocking".

She said: "It's a testament to Britain's community spirit that so many volunteers are devoting their time and energy to helping others at food banks. But I'm sure that you'll agree with me that in the 21st century no one should have to rely on charity to feed their family. Food banks should never become a permanent feature of our society."
