Our businesses need to make decisions now about investment and employment that will affect economic growth and jobs in the future. Continuing uncertainty will adversely affect communities, employees, firms and our nations in the future. Businesses across the EU and UK are clear: being able to plan for a transition of up to three years that avoids a cliff edge is critical for all of our prosperity. Until transitional arrangements can be agreed and trade discussed the risk of ‘no deal’ remains real and has to be planned for, with inevitable consequences for jobs and growth on both sides.
