Glenys Kinnock was strongly influenced by her father. He worked on the railways and was very involved in local Labour politics and the trade union movement. As a young girl she listened to her father's discussions about politics and felt very deeply about issues like nuclear disarmament and capital punishment. Aged 15 she joined the Labour Party.
