UK-EU Customs Union

Lord Lamont of Lerwick Excerpts

Thursday 29th January 2026 Lords Chamber

[Lord Lamont of Lerwick (Con)]

My Lords, it is a great pleasure for me on behalf of these Benches, this side of the House, to congratulate the noble Baroness, Lady Gill, on her admirable maiden speech. She referred to feeling a little intimidated coming here and to the experience and depth of knowledge in this House, but from her speech, it was perfectly clear that she is going to add considerably both to the experience and the depth of knowledge, and we strongly welcome her for that. She has huge experience in the European Parliament—as she said, she spent 16 years there. That is one area of expertise, but she also has expertise on housing, because she was the chief executive of a housing association. Her maiden speech was both eloquent and moving. She referred to her love of jewellery, and I am sure she will be a jewel in your Lordships’ House for a long time to come.

As was said in the noble Baroness’s excellent maiden speech, and by the noble Lord, Lord Newby, of course, it is a good idea that Britain should seek to improve its relations with the EU. But a customs union is emphatically not the way, and quite rightly, the Prime Minister has said that a customs union is a red line. We just hope that it is one of these red lines that he does not actually cross.

Brexit can be, has been and was blamed by the noble Lord, Lord Newby, for almost everything. Ministers refer to the OBR, which said that Brexit has already caused a 4% decline in GDP. But, as the noble Lord, Lord Newby, admitted, the statistic actually was that the 4% decline would happen over 15 years. Some 4% over 15 years is, on an annualised basis, a very small amount, difficult to measure accurately, especially when the effects of Brexit, as the OBR has admitted, can hardly be distinguished from those of Covid, energy prices or the war in Ukraine.

The noble Lord, Lord Newby, pointed out that goods exports to the EU remain below pre-pandemic Brexit levels. In 2024, as he said, they were 18% below the 2019 level. However, goods exports to non-EU countries over the same period were also down by 14%. So what do we conclude from this—that Brexit has caused damage to exports outside the EU? That seems rather improbable.

Over the same period, the UK’s performance in services was much better and well above its pre-epidemic levels. The fact remains that since Brexit, the British economy has moved largely in line with the larger EU economies. Italy and Germany have performed worse than Britain, France slightly better. Germany and Italy did not leave the EU and yet have performed worse than us.

A customs union is not the answer. If the question is growth, there must be a different way, and a customs union could do great harm. There would be very little gain from lower tariffs, because most UK-EU goods trade is already tariff-free. If we joined a customs union, we would have to accept tariff-free imports from those countries that the EU had negotiated trade agreements with, but we would not have the reciprocal benefit of being able to export tariff-free to those countries.

Our ability to do independent trade deals would end. We would have to renegotiate or cancel trade deals done since Brexit. The loss of the US agreement would be significant. It is actually our largest single trading partner. The pharmaceutical industry sells 25% of its exports to, and enjoys free access to, the US, while EU pharmaceuticals pay a tariff of 15%. Are we going to put this hugely important industry in danger through leaving that agreement or having to renegotiate it?

Alignment, a favourite subject of noble Lords, of regulations makes sense where individual sectors actually want it, provided that it is repealable and changeable if conditions change. Dynamic alignment, where we permanently hand over control of our laws, is a step too far and unnecessary.

It is interesting to recall how the financial services sector, which we were told after Brexit must align with the EU to survive, is now, according to recent reports in the FT—

Order.

[Lord Lamont of Lerwick (Con)]

I am just finishing—is now pleading for exclusion from any steps towards alignment. The Liberals claim a customs union would boost government revenues. They have suddenly become followers of Donald Trump, believing that “tariff” is the most beautiful word in the English language, but a customs union would mean that we would be obliged to share our customs revenues with the EU.

A customs union does not make any sense. The Prime Minister is quite right. It ought to be a red line. Gladstone would have been horrified at the stance of the Liberal party. He would have called what it is putting forward the road to servitude. It makes no sense.

[Lord Katz (Lab)]

My Lords, before we come to the next speaker, I just remind your Lordships’ House that this is a time-limited debate, and we also have a number of maiden speeches, which will obviously go a little over the speaking limit. We want to leave enough time for the Minister to respond to the many questions that your Lordships will have. We ask speakers to please stick to the four-minute speaking time.
