Dates for byelections
In England, all current vacancies which do not fill a term ending in 2021 will be held on 6 May 2021, the ordinary day for local elections. The Cabinet Office has confirmed that local elections teams should not plan on this date being brought forward. Regulations in Wales require outstanding byelections to be held in a period between 1 March and 6 May 2021.
