My partner, Megan Davies, who has died aged 67, was for many years Cardiff’s highly regarded branch secretary of the Society of Telecom Executives, now part of the Prospect union.

She was a lifelong socialist, a supporter of Socialist Worker and, until her recent ill health, was a regular at Palestine, anti-war and anti-racist protests. At her funeral Cor Cochion, a socialist choir, gave a passionate rendition of Nkosi Sikelel’ iAfrika, the South African national anthem. She used to sing it with Jen O’Keefe, her vocalist partner, at the Blue Dragon folk club and Frank Hennessey’s folk club at BBC Cardiff.

Born in Belsize Park, north London, to Jean (nee Roderick), a teacher, and Owen Davies, an academic, Megan attended Camden school for girls. The family moved to Cardiff when her father got a post as a professor of physics at Cardiff University. Megan gained a degree in French there (1981) and taught for a year in France, but returned to Wales and retrained as a computer programmer, taking a job with British Telecom in 1984.

She remained there until early retirement in 2015, and it was through trade unionism that she and I met. When we became partners in 1995 she was able to return to her north London roots, and we divided our time between Tottenham and Cardiff until Covid in 2020 and my serious illness in 2022 meant that we spent a lot more time in the Welsh capital.

It was in London that Megan, a keen real ale drinker, became friendly with brewers and others at the beginning of the “craft beer” boom, with breweries such as Beavertown, Pressure Drop and Redemption, based in Tottenham.

She made many friends and was someone who delighted in the conversation and community that taprooms and pubs could bring. In addition, she was a big sports fan, supporting the Welsh rugby team, and also Spurs, whose every wrong move she watched avidly, while I preferred to hide behind the sofa. Above all cricket was her passion, and she attended games at Sofia Gardens, Lord’s and the Oval.

Socialists and trade union activists are often seen as one-dimensional people obsessed with the cause. Megan was passionate about her politics but she had a hinterland, a life lived to the full, which touched many across a wide range of activities.

She is survived by me, her sister, Bronwen, and her brother, Simon.
