Ex-chiefs demand more forces cash
Britain's armed forces are over-stretched and under-funded, a group of former senior military leaders and politicians has warned.
They have formed the UK National Defence Association, led by three ex-chiefs of the defence staff.
One of them, Gen Lord Guthrie, told BBC News: "We are quite honestly struggling. I don't know much longer the forces can go on like this."
The group says defence spending should be about 3% of gross domestic product.
The defence budget has been set at £34bn for next year - about 2% of GDP.
