MORE cuts in UK Government spending have already been identified, Danny Alexander has admitted.

Experts have warned that after the 2015 General Election whoever is in power might have to raise taxes by £6 billion.

Speaking just 24 hours after Chancellor George Osborne set out where the additional £11.5bn of savings would be made across Whitehall departments for 2015/16, his deputy said similar levels of reductions would have to be delivered in the years 2016/17 and 2017/18.

The Institute of Fiscal Studies questioned if similar levels of cuts could be made between 2016 and 2018 and said taxes may have to rise.

But, the Treasury Chief Secretary said: "We are going to do further efficiency reviews of departments because we want to maintain the momentum of making government more efficient."
