S&P credit analyst David Beers said the ratings agency had based its outlook revision "on our view that, even factoring in further fiscal tightening, the UK's net general government debt burden may approach 100% of GDP and remain near that level in the medium term"...
John Hawksworth, head of macroeconomics at PwC, said there would need to be a "fiscal squeeze" – a combination of tax rises and public spending cuts – building up to between £115bn and £133bn a year by 2018, equivalent to about £5,000 for every family in the country.
He also said the government should consider raising the retirement age more quickly to combat the effects of increased longevity. "Provisions for these potential costs should be made sooner rather than later."
