Either the government is publishing Brexit documents without reading them through properly - or they're hoping you don't read them either.

The Treasury published their crucial white paper on customs arrangements after Brexit today.

They've called it a "significant step" in preparing for Britain to leave the EU, and will "pave the way for legislation that will ensure the UK is ready for the first day after exit."

But those who have read the document were overcome with a sudden sense of deja-vu.

Here's what paragraph 5.12 says:

...and here's the very next paragraph:

Hmm...

A Treasury spokesperson confirmed to the Mirror that the paragraph had been repeated in error, but that nothing had been left out of the paper.

Meanwhile, Theresa May has been 'updating' MPs on the implications of her Florence speech in her first appearance in the House of Commons since her disastrous conference keynote.

She insisted Britain's agreement for single market and customs union access should operate on the "same rules and regulations" during the transition period.

The Prime Minister said the UK will leave "full membership" of both the single market and customs union in March 2019 but wants a "new agreement" on the same basis during the transition.

Former Labour leader Ed Miliband appeared to be left asking "What does that even mean?" after Mrs May responded to his request to detail the transition arrangements.

Mrs May also sidestepped questions from Labour MPs about whether the Government has received legal advice about the potential to revoke the Article 50 notice and thereby halt the Brexit process.

Speaking in the Commons, Mr Miliband said of Mrs May: "She has said very clearly that she believes that on her plans we will be out of the customs union and the single market by March 2019.

"That was not the impression I got from the Florence speech.

"Could she therefore explain how the arrangements she is seeking for the transition differ from being members of the single market and the customs union for the period of the transition?"

Mrs May replied: "As we leave the European Union in March 2019 we will leave full membership of the customs union and full membership of the single market.

"What we then want is a period of time when practical changes can be made as we move towards the end state - the trade agreement - that we will have agreed with the European Union.

"We have to negotiate for that implementation period what the arrangements would be.

"We have suggested that that should be a new agreement, an agreement that we should be able to operate on the same basis and on the same rules and regulations."
