The Department for Work and Pensions (DWP) is in the process of reviewing the State Pension age, which is currently 66 for men and women.
The age at which people can begin claiming their State Pension is re-evaluated frequently to ensure that it remains fair as life expectancy increases.
According to the DWP, the review is being carried out because "when the State Pension was introduced in 1948, a 65-year-old could expect to spend 13.5 years receiving the benefit, around 23 per cent of their adult life".
