Further the 'default' retirement ages (originally 60 for women, but rising in line with the state pension age, and 65 for men) have been abolished for anyone who was not told before 6th April that they'd have to retire when they reached the relevant age.
Prior to the recent change in the law, employers could simply throw out employees when they reached the state pension age, on the grounds that they'd retired. The employees could not claim for 'unfair dismissal' because the right to do so was terminated upon reaching state pension age.
However now (unless the employer can prove to an Employment Tribunal that there is a valid reason for forcing an employee to retire) nobody can be forced to retire at any specific age (and the right to claim for 'unfair dismissal' lasts for life).
