As a responsible Government, we have been preparing to minimise any disruption in the event of no deal for nearly three years.

The Cabinet Office has allocated £58.8m in 2019/20 for EU Exit activity. The costs for each scenario cannot be readily separated, given the significant overlap in plans in many cases.
