Antonia Louise Antoniazzi[1] (born 5 October 1971[2]) is a Welsh Labour Party politician who has been the Member of Parliament (MP) for Gower since 2017.

[8] In June 2019, Antoniazzi urged ministers to allow the use of medical cannabis by "all who need it", citing the case of 12-year-old Billy Caldwell whose epilepsy was alleviated through use of the drug.

[22] Antoniazzi is a co-sponsor of Kim Leadbeater's Terminally Ill Adults (End of Life) Bill on assisted suicide.

Jeremy Corbyn had instructed his MPs to abstain in a vote which Britain would remain in the single market by joining the European Economic Area (EEA).

The delegates were criticised by Pink News for removing references to anti-LGBTI attacks in the UK, a condemnation of anti-trans movements and a call to withdraw funding from anti-LGBTI groups or authorities; in turn the delegates were defended by Debbie Hayton, a gender-critical activist, for protesting the removal of sex-essentialist language she considered important for non-trans women.

[31][32] In July 2022, Antoniazzi submitted an application on behalf of the gender critical group Labour Women's Declaration for them to have a stand at the party's annual conference in Liverpool, which was subsequently denied.
