This means the pension age for women will increase to 65 by November 2018 and then increase again to 66 in April 2020. The move up to 66 years will be managed by increasing the state pension age three months in every four month period.
Steve Webb, the Minister of State for Pensions, said: "We are all living longer than ever before, and it is important for government to take this into account when developing policy.
"As longevity increases it is only fair that costs are shared among the generations. Accordingly, the Government has decided to bring forward the increase in the state pension age to 66.
"Although women will experience the rise in the state pension age more quickly than previously planned, they will still draw the state pension for longer, and our 'triple guarantee' means someone retiring today on a full basic state pension will receive £15,000 more over their retirement than they would have done under the old prices link."
The DWP added: "This decision means a total of 4.9 million people in Great Britain will have their SPA revised. Of these, 4.4 million men and women will have an increase in SPA of a year or less."
