Your representatives within the European Parliament are none.
The Conservatives voted for the Brexit Withdrawal agreement, so the UK has had no representatives in any of the EU's decision making bodies since 31st January 2020.
We will however continue to follow all the EU laws and European Court of Justice rulings that were implemented up to January 2020. These were converted into UK law as part of the Withdrawal Act. Since the 1st January 2021 we have been subject to the new third-party trading relationship the Conservatives negotiated with the EU.
The implications of these new arrangements will unfold and become apparent over the course of 2021 and beyond.
