MILITARY EXPENDITURE

DEFENCE spending must increase by 50 per cent to protect the special relationship with the U.S., according to a report by MPs.

Military expenditure, currently around 2 per cent of national income, must also rise for the UK to maintain its influence in NATO, they said.

The MPs reiterated calls for spending to go up to 3 per cent of GDP – which would be equivalent to an extra £2billion a year.

Without this, UK forces would struggle to maintain their ability to work alongside the US military, diminishing their usefulness as allies, the Commons defence select committee said.

The report added some in the US believe Britain’s defence capabilities have “slipped” and that concerns have been raised about the UK’s ability to operate independently.

The report reveals US defence secretary James Mattis had been referring to Britain when he said recently one of America’s allies had cut capacity “to the point where it could no longer speak with strength”.

Conservative MP Julian Lewis, the committee chairman, warned anything less than an investment of 3 per cent of GDP “endangers us and our allies”.

It comes as Defence Secretary Gavin Williamson is locked in a battle with Theresa May over defence spending.

Dozens of Tory MPs could vote to block the Budget unless the Prime Minister increases military spending. It follows reports that Mr Williamson had told military chiefs he could bring down Mrs May if she refuses to back him in his fight to get an extra £2billion a year from the Treasury.

The report, published ahead of next month’s NATO summit in Brussels, also warned the UK military risks becoming “irrelevant” because of the time it would take to deploy forces. Currently, it would take 20 days to deploy a mechanised brigade and 90 for a division.

It suggested Britain should take the lead in defending the North Atlantic, bolstering its anti-submarine warfare capability to defend against a ten-fold increase in Russian submarine activity in the area.

The report said: “If the UK wishes to maintain its leadership position within NATO and continue such fruitful defence relations with the US, then it will have to invest more in its armed forces. Diminished capacity reduces the UK’s usefulness to the US and our influence within NATO. The Government must not allow this to happen.”

Mr Lewis said: “An increased commitment, in the face of new and intensified threats, means further investment is essential. Where percentage of GDP for defence is concerned, our mantra must be: ‘We need 3 to keep us free’.

“Anything less is simply rhetoric which endangers us and our allies.”
