She was speaking after announcement of the deal, which includes removal of some checks on animal and plant products, as well as moves on security.

“Alliance has always said the key to resolving the frictions imposed by Brexit has been closer alignment between the UK and EU, and today is proof of that,” said Mrs Long.

“Despite not creating this situation, we have consistently come to the table with pragmatic solutions. We were the first party to propose an agreement to ease food, plant and animal movements across the Irish Sea. The deal that has been reached on agri-food will benefit not only Northern Ireland, but also the UK and EU more widely.

“While details are still emerging on today’s deal, it seems to be a first, positive step in a closer and better relationship between the UK and EU. However, further work is clearly required to address issues around customs and veterinary medicines.

“Enormous damage has been caused by the approach of the previous UK Government. It is vital this package is implemented in good faith and Government continues to take steps to align more closely with Europe to remove red tape, grow our economy and ensure our businesses can trade seamlessly on a north-south and east-west basis.

“Our people and businesses will only benefit if that is case.”
