From the Wikipedia page on David Kurten 
In the London Assembly, he confronted Khan on what he called "gender ideology" by promoting "traditional family values", and as a Brexit campaigner he opposed Khan's support for the EU and call for a second referendum.
In January 2020, Kurten announced he would run as an independent candidate in the upcoming London mayoral and London Assembly elections (then scheduled for May 2020, but both elections were postponed to 2021 due to the COVID-19 pandemic). Kurten founded a new political party in 2020: the Heritage Party was registered with the Electoral Commission that October. Kurten finished 15th with 11,025 votes in the mayoral election, while his party finished 13th on the London-wide list with 13,534 votes.
In December 2020, Kurten rejected a COVID-19 vaccine, and was denounced by the Conservative mayoral candidate Shaun Bailey, who saw this as irresponsible for an elected politician. Lockdowns in response to the coronavirus pandemic have been condemned by Kurten, who is the only elected politician in the UK who has regularly attended the ‘freedom rallies’, a series of protests against government measures to combat the pandemic.
The Heritage Party got 1.6% of the vote, coming fourth, in the 2021 Hartlepool by-election with 468 votes. In the 2021 London elections, Kurten received 0.4% of the vote in the mayoral election, coming fifteenth, while the Heritage party list, headed by Kurten, received 0.5% in the Assembly vote. He was, thus, not re-elected.
