Commenting on the announcement of a Brexit deal being agreed, ADS Chief Executive Paul Everitt said: “The UK aerospace, defence, space and security industries welcome the agreement of a deal on the UK’s future relationship with the EU. A deal provides the best framework for our relationship with European allies and industrial partners.

“We recognise the deal does not meet all our ambitions and will examine the full legal text to ensure priority areas including aviation safety and chemicals regulation, customs and border control, and Northern Ireland are appropriately addressed.

“There is now just one week remaining until the end of the transition period, and it will be difficult for businesses to be ready in time.

“The Government must issue swift, clear and comprehensive advice to businesses on preparations, and work urgently to put all necessary arrangements in place.”

ADS is the UK trade organisation representing the Aerospace, Defence, Security and Space sectors, with more than 1,100 member businesses.
