Women will have to wait up to another 150 years for equal wages to their male counterparts,  according to research published today in The Times newspaper.

The gap in pay between men and women had been narrowing for the  past 30 years, but has now started to become static, analysts at the Centre for Economic Performance at the London School of Economics said.

The imbalance was blamed partly on the penalisation of women who take career breaks to have children and then work part-time after giving birth.

However, the report found that even women who worked full-time  and did not take career breaks would still earn 12% less than their male counterparts after ten years, due to discrimination and  ineffective government policies.

'We are used to each generation of women making progress relative to the one before,' said the report, authored by LSE Professor of Economics Alan Manning.

'But this process has slowed with the current generation doing only slightly better than the previous one. It will take 150 years for this gap to disappear,' he added.
