Prime Minister Rishi Sunak and European Commission President Ursula von der Leyen are meeting for "final talks" to resolve post-Brexit trade issues in Northern Ireland.
Downing Street says Sunak aims to fix practical problems on the ground, ensure trade flows freely within the UK, safeguard Northern Ireland's place in the Union, and return sovereignty to the people of Northern Ireland.
If a final deal is agreed upon, Sunak and von der Leyen will hold a short joint news conference.
This comes after months of intensive negotiations over the protocol, which governs trade in Northern Ireland, and which has kept the territory in the European single market.
The United Kingdom and the European Union are nearing a critical agreement over post-Brexit trade rules for Northern Ireland, which is one of the most bedeviling legacies of Brexit.
Prime Minister Rishi Sunak and European Commission President Ursula von der Leyen are holding final talks — their first in-person meeting in months — today to work out the final details.
The joint statement from Downing Street and the Commission has confirmed that the two leaders will discuss the "range of complex challenges around" the protocol on Ireland and Northern Ireland.
They aim to work towards "shared, practical solutions" to the problems.
If a deal is reached, it could "resolve one of the most bedeviling legacies" of Brexit.
However, there are seven tests that the new pact will have to meet in order to win the Democratic Unionist Party's backing.
The party has called on Sunak not to try to "bounce" backbenchers into backing the new deal.
While this breakthrough could mark a promising sign for the future of UK-EU relations, including in trade and security, it is still possible that a deal could fall apart.
