Brexit ‘largely to blame’ for £31bn loss to UK economy, study finds

5.2 per cent GDP shortfall ‘mostly’ down to Britain’s exit from EU, according to top think tank

Brexit is “largely to blame” for billions being lost in trade and tax revenues in recent years, according to a new study by top economists.

The Centre for European Reform (CEF) said that by the end of last year, Britain’s economy was 5.2 per cent – or £31bn – smaller than it would have been without Brexit and the Covid pandemic.

“We can’t blame Brexit for all of the 5.2 per cent GDP shortfall … but it’s apparent that Brexit is largely to blame,” said John Springford, author of the CEF study.

The CER modelled the performance of a “doppelganger” UK – if the nation had remained inside the EU’s single market – using data from other advanced economies similar to the UK.

Mr Springford said “disentangling” the economic effects of Brexit and Covid in recent years was “difficult” – but said it was clear that the bigger negative impact had come from Brexit.

The economist argues that a huge gap between the current UK and his “doppelganger” economy had opened up before the pandemic struck in the spring of 2020.

Mr Springford said the sluggish economic performance after the end of lockdowns in 2021 also showed that the “sizeable” shortfall was “mostly Brexit and not Covid”.

“The UK ended Covid restrictions sooner than many of its peers, thanks in part to starting its vaccination campaign early in 2021,” he said. “That should have made its recovery from Covid faster than other countries, not slower.”

The CER study said it was “hard to avoid the conclusion that Brexit has severely curtailed GDP, investment and goods trade”.

The report added: “British politicians may find it difficult to ignore the central role of Brexit in the UK’s economic problems for much longer.”

It comes as British firms point to the post-Brexit red tape which is continuing to create costly hold-ups in trade with the EU.

One seafood firm in Northumberland spoke out about the “ridiculous” paperwork which almost caused a £50,000 delivery to be destroyed, since a form signed 43 times did not include a printed name.

The Coquet Island Shellfish Company told the BBC the issue cost the firm up to £15,000 to sort out after several delays. “There have been no discernible benefits of Brexit. Everything takes longer and costs more,” said sales director Jane Pedersen.

An influential committee of MPs recently warned that it was uncertain whether the post-Brexit free trade agreements negotiated by Boris Johnson’s government will provide any “actual economic benefits”.

No 10 confirmed on Friday that controversial new Brexit legislation – designed to take unilateral action to stop checks agreed with the EU as part of the withdrawal deal – will be published in the Commons on Monday.

Conservative party grandee Ken Clarke said the “vast majority” of peers will back attempts to block the bill and “hold it up for a considerable time”.

Meanwhile, Tory peer David Frost, the former Brexit negotiator, has said he is “thinking” about standing as an MP. “We’ll see if the opportunity arises and it might and it might not, we’ll see,” he told LBC. “I am thinking about it.”
