The former Defence Secretary has said he quit for ‘our country’ after refusing Sir Keir Starmer’s cash offer for the Armed Forces.In his resignation speech, John Healey told MPs he had ‘loved’ his job but believed his decision was ‘necessary in securing the future’ of the UK’s military.Healey left the Ministry of Defence last week after Sir Keir backed Chancellor Rachel Reeves’ offer of only £10 billion in new funding for the Armed Forces - despite the growing threat to UK security posed by Russia.That settlement will put Britain in greater jeopardy according to Mr Healey and will increase the threat to troops.Healey’s harrowing assessment was backed earlier today when the head of the UK’s Armed Forces gave evidence to a parliamentary committee.Air Chief Marshal Sir Richard Knighton told the House of Lords fewer military operations would be possible based on the funding settlement backed by the PM.While UK defence spending has risen from 2.3 per cent of GDP to 2.6 per cent of GDP since the last General Election, the current level of investment falls far short of national security requirements.Service chiefs estimated an additional cash sum of £28 billion over the next four years was required to pay for higher running costs and new equipment.
