Antoniw comes from a Ukrainian family, with a Danish mother[3] and came to the UK as a result of his father seeking refugee status in the UK following World War II.[4]
He was a practising solicitor before his election to the Senedd, specialising in personal injury. Antoniw was a partner in Thompsons Solicitors, the specialist trade union solicitors, with whom he began his training in 1980.[6] He is a trustee of the Welsh Refugee Council.[5][6]
Personal life
Antoniw fostered dozens of children in the 15 years prior to his election, saying "When you are fostering, it brings immense quality. It is very challenging – and can be dependent on the nature of the fostering, whether the child is disabled or older children where there are difficulties. But my experience in the mixture of fostering that we did, was that it does add value to your life. Seeing children developing and beginning to blossom to some extent during the fostering process is very rewarding."[7]
Political career
Antoniw was a leading member of the Wales Anti-apartheid Movement (WAAM) during the 1980s.[8] In 1981 he was elected as a Labour councilor to the South Glamorgan County Council for the Court ward, gaining the seat from the Conservatives. He was re-elected in 1985 but did not seek re-election in 1989.
He was appointed as Counsel General for Wales in June 2016. However, he departed from this role in November 2017 as part of a Government reshuffle, being replaced by Jeremy Miles.[11]
Antoniw is a fluent Ukrainian speaker and has used his knowledge of the language when meeting with Ukrainian officials including deputy prime minister Volodymyr Groysman at international summits, such as the European Union Committee of the Regions. He has stated that he is a supporter of Ukrainian accession to the European Union, a supporter of the country joining NATO, and does not support Ukrainian federalism.[4] Antoniw visited Ukraine just prior to the 2022 Russian invasion of Ukraine alongside Plaid Cymru leader Adam Price in order to "show solidarity with workers and minorities" as they met workers, LGBTQ+ people, ethnic minorities and human rights defenders.[12]
