There could be further disruption to trade with the EU this year if more is not done to improve post-Brexit border arrangements, MPs have warned.

The cross-party Public Accounts Committee (PAC) said the main impact of Brexit on UK firms had been “increased costs, paperwork and border delays”.

But it said things could worsen this year as new import controls come in.

The government said it continued to ensure businesses “got the support they need to trade effectively with Europe”.
