British parliamentarians have taken a critical stock of Brexit and warned of further consequences.

The Accountability Committee stated in a report presented on Wednesday that the main impact of leaving the EU for British companies is “increased costs, paperwork and delays at the border”.

New import controls, which have been in effect since the beginning of the year, could further worsen the situation.

The Public Accounts Committee warned that delays are also possible for private trips as soon as traffic returns to normal.

The committee also criticized the government's plan to create the world's most effective border controls by 2025 as "optimistic given the current status".

"We believe the Government needs to do much more in the short term to understand and minimize the current burden on those who trade with the EU," said Meg Hillier, the committee chair of the opposition Labor Party.

The government pledged to support companies trading with Europe.

As of January 1, 2021, the UK is no longer a member of the EU Customs Union and Single Market.

A short-term agreed trade agreement ensures that trade with the EU can continue to be largely duty-free.

However, new regulations are still causing delays.

Great Britain has also been controlling EU imports more closely since the beginning of the year, which also impedes the flow of traffic.

Most recently, there were long truck traffic jams in front of the important port of Dover on the English Channel.

Only on Tuesday did Prime Minister Boris Johnson appoint MP Jacob Rees-Mogg as "Secretary of State for Brexit Opportunities".
