Rules that enable employers to force workers to retire when they reach the age of 65 are "at odds with anti-age discrimination" legislation, it has been claimed.
Writing in the Daily Mirror, Paul Routledge described employment law for people over 65 as "a mess", adding that it needs to be sorted out "sooner rather than later".
He made his comments following a high court ruling last week by Mr Justice Blake that current laws comply with a European Commission directive against age discrimination.
The verdict came as a blow to Age Concern and Help the Aged, which launched a legal campaign to scrap the mandatory retirement age in 2006.
Mr Rouledge called on the government to review the law.
He said the retirement age in Britain is going up to 67 and then 68, and eventually possibly 70.
"It cannot be fair for men and women to have to work for several years after 65 in a legal limbo with no rights at work," he added.
There should be a clause in the Equality Bill coming before parliament abolishing default retirement, Mr Rouledge concluded.
