Chancellor George Osborne has said that Britons will have to work longer before being entitled to a State pension.
Unveiling a comprehensive spending review which could result in almost half a million job losses over four years, Mr Osborne said: "Tackling this budget deficit is unavoidable."
The chancellor than announced that people would have to work longer before they get their state pension.
He said the state pension age for men and women will reach 66 by the year 2020 - four years sooner than previously expected.
He said this would involve a gradual increase in the state pension age from 65 to 66, starting in 2018.
The move would save over £5 billion a year - "money which will be used to provide a more generous basic state pension as we manage demographic pressures", said Mr Osborne.
On the job losses that will result, Mr Osborne confirmed that the Office for Budget Responsibility had estimated that 490,000 could go over the four years.
But he sought to reassure the public, saying: "Much of it will be achieved through natural turnover, by leaving posts unfilled as they become vacant. Estimates suggest a turnover rate of over 8% in the public sector.
"But yes, there will be some redundancies ... that is unavoidable when the country has run out of money.
"We feel responsible for every individual who works for the Government, and we will always do everything we can to help them find alternative work.
"In fact, in the last three months alone the economy created 178,000 jobs."
Mr Osborne indicated that even the Queen was doing her bit.
He said she had agreed to a one year cash freeze in the Civil List for next year.
He added: "Going forward, she has also agreed that total Royal Household spending will fall by 14% in 2012/13 while grants to the Household will be frozen in cash terms."
