Is Great Britain in the common market?

Great Britain is no longer a member of the European Union's Single Market, having officially left the EU on January 31, 2020. However, it does have a trade agreement with the EU that allows for some level of market access. While it is not part of the EU's Common Market, it engages in trade with EU countries under the terms of the Trade and Cooperation Agreement. Additionally, Great Britain has been exploring trade partnerships outside of Europe.
