The granddaughter of an Irish suffragette has smashed windows at Dublin Castle to mark 100 years since women got the right to vote.

Hanna Sheehy Skeffington smashed windows at Dublin Castle, the seat of British power, at 5am on 13 June 1912, in protest at women not having the right to vote.

She was arrested and taken to Mountjoy Prison, where she went on hunger strike.

Nearly six years after the protest, on 6 February 1918, women got the right the vote for the first time.

Today, her granddaughter Micheline Sheehy Skeffington, dressed as a suffragette, reenacted the scene.

The Representation of People Act 1918 allowed some women over the age of 30 and all men over the age of 21, to vote in general elections.

Dr Sheehy Skeffington said it is women's place to take direct action for equality.

She said her grandmother would be surprised by how little has been achieved in terms of equal rights for women in the past 100 years.

"We haven't got parity, we haven't got equal pay, we're not equal in the government, we're not equal in the universities," Dr Sheehy Skeffington said.

"We do not command the respect we should. I think she would be a little bit surprised."

Dr Sheehy Skeffington added that women should be aiming for 50/50 representation in politics and that a change in attitudes towards women was needed in society.

"We are perfectly capable of being in government," she said. "We are not saying about putting women in who aren't capable. But there are a lot of men who get in who aren't that capable either.

"If more women were in power, we might have a bit more respect and command a bit more respect."

Born in 1877, Hanna Sheehy Skeffington dedicated her life to tackling injustice and women's inequality.

In 1908, she founded the Irish Women's Franchise League, a militant suffrage organisation, with fellow campaigner Margaret Cousins.

In December 2014, her granddaughter won an equality tribunal case she took against the NUI where she works.
