What date in 2020 was set for the UK to leave the EU?

The United Kingdom officially left the European Union on 31 January 2020. This date marked the end of a membership that lasted for 47 years, following a 2016 referendum where a majority of voters chose to leave. The transition period that followed lasted until 31 December 2020, during which the UK and the EU negotiated their future relationship, but the formal exit occurred at the end of January. This significant date is often cited in discussions about Brexit, as it initiated a series of changes to laws, regulations, and relationships both domestically and internationally, impacting various sectors.
