A Labour review could pave the way for Britain to copy other European nations and raise the state pension age to 70.
Dr Suzy Morrissey has been appointed to prepare an independent report as part of the Government's review of the official retirement age that is due to conclude in 2029.
The expert said she had been asked to 'make recommendations on a framework' that ministers can use 'when considering future state pension age arrangements'.
In her call for evidence, published yesterday, Dr Morrissey said her work was taking place amid the 'long-term demographic pressures the country faces'.
She set out how pensioners are forecast to make up a quarter of the adult population within the next 50 years because of improvements in life expectancy.
