A special beer brewed with rhubarb has been unveiled to celebrate the achievements of Yorkshire's first female MP.
The 4.3% pale ale was brewed in honour of miner's daughter Alice Bacon, born in Normanton near Wakefield and elected as Labour MP in Leeds in 1945.
Baroness Bacon became a high-profile Home Office minister, overseeing the abolition of the death penalty.
Beer glasses were to be raised to her in Westminster's Strangers Bar.
The beer is already sold in bottles at working men's clubs in Normanton, originally opened by Baroness Bacon.
She grew up in a mining community during the 1930s depression and was elected Labour MP for Leeds North East in 1945.
Rachel Reeves, Labour MP for Leeds West who has written a Baroness Bacon's biography, called her a "pioneer".
"Alice Bacon was born into a world where women were unable to vote, yet went on to become Yorkshire's first female MP and a high-profile minister under Harold Wilson, spearheading the introduction of comprehensive schooling," she said.
