A significant breakthrough in UK-EU talks occurred late Sunday night, according to government sources, resolving key issues—primarily fishing rights—that had remained stumbling blocks in negotiations, according to BBC.

The progress comes as Prime Minister Keir Starmer chairs a gathering of European Union leaders in London to rebuild post-Brexit relations. Discussions are anticipated to include defense, commerce, fishing, and a prospective youth mobility plan.

The UK formally departed the EU on January 31, 2020. While Labour portrays the conference as a new beginning, the Conservative Party has criticized it as a "surrender summit”, BBC reported.

After a period of relative silence on Brexit, the renewed focus marks a potentially pivotal moment in the UK’s relationship with the EU.
