A mother who lost her son in the Hillsborough disaster has won the Women of the Year Special Award on behalf of the families affected by the 1989 tragedy.

Margaret Aspinall, chairwoman of the Hillsborough Family Support Group, whose son James died in the disaster, was presented with the award by Theresa May in recognition of the families' persistent search for truth and justice.

The Prime Minister said she was "honoured" to give the award at the ceremony on Monday afternoon in London, adding: "Having lost their loved ones in the most appalling circumstances, they then spent 27 years searching for the truth with extraordinary dignity.

"This April, when the fresh inquests delivered their conclusions, they made clear to the whole nation what the Hillsborough families have known to be true from the beginning - that the fans were blameless."

Mrs May continued: "Thanks to their resolve we now know the truth about what happened that day. This award is for all those who lost their lives at Hillsborough and their families who have shown immense courage and determination."

More than 400 women attended the lunch and awards, where six were recognised for their "courage, resourcefulness, flair and for their selfless actions".

Sandi Toksvig, president of Women of the Year, said: "For over 60 years, Women of the Year has proudly recognised and celebrated the achievements of some of the world's most incredible women.

"These women range from the super famous to unsung heroines who are the backbones of charities, industries and indeed every profession possible.

"The remarkable women who make up the attendees and winners at this year's Lunch are being recognised for their work making the world a better place."
