Economists at the Centre for Economics and Business Research predict a £30 billion deficit in 2019-20 as the Chancellor is hemmed in by commitments not to raise some taxes, as well as ringfenced spending plans. “It is very likely that within a couple of years the Chancellor will be faced with the unenviable task of deciding between cutting long-term investment spending or giving up on the self-imposed goal of eliminating the deficit,” senior economist Nina Skero said.
