The Democratic Unionist Party (DUP) has expressed reservations about Rishi Sunak's new Brexit deal for Northern Ireland.
Ahead of the crunch vote in the House of Commons, the party said that the new deal doesn't solve the "fundamental problems" with the protocol it is designed to replace.
The DUP has not yet made an official announcement on whether it will support the agreement, but its statement suggests that there is more work to do to address the issues that led to the collapse of powersharing in Stormont.
The Woodhouse Correspondent wrote that the DUP's position on the new Brexit deal reflects its concerns about the Northern Ireland Protocol.
The party's statement suggests that the new deal, known as the Windsor Framework, does not address some of the key issues that have caused difficulties with the protocol.
The DUP has previously complained that the protocol has resulted in a border between Northern Ireland and the rest of the UK, and has been overly burdensome on businesses in the region.
In contrast, Sky News noted that the new deal has been designed to address many of the DUP's concerns.
The Windsor Framework replaces the protocol with a new set of arrangements that are intended to preserve Northern Ireland's place in the UK's internal market while avoiding the creation of a hard border on the island of Ireland.
The deal also includes provisions to ensure that Northern Ireland's institutions are able to function effectively, and to address issues such as customs and regulatory alignment.
Despite the DUP's reservations, it is unclear whether the party will ultimately back the new Brexit deal in the House of Commons vote.
The outcome of the vote is expected to be closely watched, particularly as some Conservative MPs have signalled their opposition to the agreement.
If the deal is rejected, it could potentially lead to a breakdown in talks between the UK and EU, and further uncertainty for Northern Ireland's place in the wider Brexit process.
