At Matrix Chambers, the ‘very incisive’ Helen Mountfield KC is well-versed in assisting returning officers, the Electoral Commission, individual candidates and political parties with a range of election law issues, and is singled out for her extensive experience in handling election petitions. Gavin Millar KC and the ‘tough cross-examiner’ Tom Gillie successfully represented the Labour Party in Cooper v Evans, where an injunction application was brought by the Conservative Party candidate against a Labour online campaign advert during the Tamworth by-election – the Conservative candidate claimed that the advert was in breach of s.106(1) of the Representation of the People Act 1983 as it included a false statement of fact in relation to his personal character and conduct. Sarah Sackman was elected as Member of Parliament for Finchley and Golders Green in the 2024 general election.
