TENS of thousands of women from Wiltshire could be affected by a High Court ruling rejecting a challenge against controversial changes to the state pension age. Nearly 4 million women born between April 6 1950 and April 5 1960 have been affected by the changes, made by successive governments, to raise the state pension age for women from 60 to 66.

Approximately 31,000 in Wiltshire were born within that period, according to population estimates and at least 59 per cent of are yet to hit their state pension age.

Initial government plans would have seen the pension age rise in phases, from 60 in 2010 to 65 in 2020.

But in 2010, the coalition government accelerated the plans, raising the retirement age to 65 in 2018 and 66 by 2020.

Campaign group Women Against State Pension Inequality argues the changes have caused financial hardship for hundreds of thousands of women, who may struggle to find suitable employment.

Many were not allowed to join private company pension schemes until the 1990s, it said, while others are carers or in poor health.

Two women – Julie Delve, 61, and Karen Glynn, 63 – took the Department for Work and Pensions to the High Court with the support of campaign group Backto60.

They argued that raising the pension age had unlawfully discriminated against them on the grounds of age and sex, and that they were not given adequate notice of the changes.

But High Court judges Lord Justice Irwin and Mrs Justice Whipple dismissed the claim "on all grounds".

In their ruling, the judges stated: "We are saddened by the stories we read in the evidence lodged by the claimants. But our role as judges in this case is limited.

"The wider issues raised by the claimants, about whether these choices were right or wrong or good or bad, are not for us; they are for members of the public and their elected representatives.

"There was no direct discrimination on grounds of sex, because this legislation does not treat women less favourably than men in law.

"Rather, it equalises a historic asymmetry between men and women and thereby corrects historic direct discrimination against men."

In a statement after the ruling, Unison general secretary Dave Prentis said: "This is a terrible blow for the millions of women who will have been hoping for a very different outcome today.

"The decision to hike the state pension age with next to no notice didn't just throw their retirement plans up in the air, it also left many women on lower incomes really struggling to make ends meet."

Campaigners have now called on Parliament to intervene on their behalf.

A DWP spokesman welcomed the judgment, adding: "It has always been our view that the changes we made to women's state pension age were entirely lawful and did not discriminate on any grounds.

"The court decided that arguments the claimants were not given adequate notice of changes to the state pension age could not be upheld.

"This follows the extensive communications that DWP made to publicise these changes over many years."

He added that raising the state pension age in line with changes to life expectancy had been the policy of successive governments over many years.
