LONDON: Prime Minister Theresa May led tributes to the “heroism” of campaigners on the centenary on Tuesday of women winning the right to vote in Britain, as a host of events honouring the Suffragette movement were held.

In a speech in Manchester − the birthplace of Suffragette leader Emmeline Pankhurst − May will honour the women who “transformed British democracy.”

Campaigners meanwhile hope to make fresh calls for Suffragettes who were jailed while fighting to win the vote for women to be pardoned posthumously.

The Fawcett Society, a British charity campaigning for gender equality and women’s rights, are among those urging the country’s interior minister Amber Rudd to officially pardon more than 1,000 women jailed during their struggle for equality.

Relatives of the Suffragettes, as well as leading lawmakers including Ruth Davidson, the Scottish Conservative leader, have backed the calls.

“Voting was a value judgment, not an intrinsic right,” she wrote in Tuesday’s the Daily Telegraph.

“That inequality is one of the reasons why I support calls to offer a posthumous pardon to those Suffragettes charged with righting that wrong.”

Rudd told the BBC she was aware of the campaign and “completely understand where it’s coming from.” Britain’s Suffragettes adopted militant tactics in their fight for the vote, including the use of violence.

They chained themselves to railings, broke shop windows and blew up post boxes as part of their fight. They cut electricity lines, disrupted meetings and even bombed the house of a government minister.

“It is complicated,” Rudd said. “If you’re going to give a legal pardon for things like arson and violence it’s not straightforward.” - Organisers of an evening reception to launch a year-long “Vote 100” series of Suffragette events and exhibitions in Westminster have invited every living current and former female lawmaker.

It will be the largest-ever gathering of Britain’s women politicians, organisers believe.

“I look forward to joining hundreds of female Parliamentarians, past and present, to celebrate this very special anniversary,” May said ahead of the event.

“Everyone attending tonight will be there because of the heroic, tireless struggle of those who came before us.”

In parliament’s spectacular central lobby four historic acts of law will go on display together for the first time.
