MP for Gower
“A centrist Labour backbencher with high attendance who has rarely rebelled, notably opposing Nick Boles’s Common Market 2.0 motions in 2019.”
Tonia Antoniazzi is the Labour and Co-operative MP for Gower, first elected in 2017. She serves on the Liaison Committee and the Northern Ireland Affairs Committee, and has previously sat on a range of committees including Welsh Affairs and the Procedure Committee.
Her party loyalty is 100%, with attendance of 59% (above the party average of 33%). Her voting record is mixed across issues: she generally backs NHS funding and bus services regulation, while tending to oppose stricter immigration controls and the asylum system, with a mixed approach on welfare, transgender rights, and workers’ rights.
Declared financial interests include seven entries of gifts, benefits and hospitality from UK sources, two miscellaneous entries, and one visit outside the UK.
