Individuals in finance jobs may be among those who a new study has found are working beyond the age of 65.
According to figures published by the Office for National Statistics (ONS), the number of people older than this who remain in work has more than doubled over the last decade, despite the impact of the recession.
In 2001, 412,000 people over the age of 65 worked in the UK, with 106,000 of these in full-time employment.
At the end of last year, the total figure was 870,000, with 270,000 people still performing a full working week.
ONS statistician Jamie Jenkins said: "The analysis also looks at how long these individuals have been in continuous employment and it shows that around two-thirds of those in work after reaching the age of 65 have been with their current employer for over 10 years."
In January, it was announced by the government that the Default Retirement Age, which allows employees to force staff who reach the age of 65 to leave their job, is to be scrapped.
