Here are some of the main developments in the row over the Government’s analysis of Brexit’s impact on different sectors of the economy.
:: December 14 2016: Brexit Secretary David Davis tells the Commons Exiting the European Union Committee select committee: “We are in the midst of carrying out about 57 sets of analyses, each of which has implications for individual parts of 85% of the economy.
“Some of those are still to be concluded.
“We have work still to be done on justice and home affairs, so there is a fair number of things still to do. It will be as soon as we are ready.”
:: June 25: Mr Davis says on BBC One’s Andrew Marr Show: “In my job I don’t think out loud and I don’t make guesses. Those two things. I try and make decisions. You make those based on the data. That data’s being gathered, we’ve got 50, nearly 60 sector analyses already done, we’ve got planning work going on in the Customs, we’ve got planning work going on 22 other issues.”
:: Autumn 2017: By now the Government has refused to publish the analysis in response to several freedom of information (FOI) requests from MPs and others, as well as written parliamentary questions.
:: October 10: The Government refuses to say whether it has carried out regional impact assessments following a Press Association FOI request because doing so would provide a “reactionary” response that could damage the economy.
:: October 11: More than 120 opposition MPs call on Mr Davis to “come clean” and publish the economic studies. Meanwhile, Chancellor Philip Hammond confirms to the Commons Treasury Committee that the Government has a model which looks at Brexit’s potential impact on economic sectors, as well as regions of the UK.

:: October 25: Mr Davis tells the Exiting the EU Committee the assessments are in “excruciating detail” and that Prime Minister Theresa May has read “summary outcomes” from them.
:: November 1: MPs approve a Labour motion unopposed which asks for a “humble address” requesting the Queen to tell Mr Davis to release the documents to the Exiting the European Union Committee.
Earlier, Brexit minister Robin Walker told the Commons: “The analysis is not a series of 58 economic impact assessments. It is a cross-sectoral analysis. It is not just work undertaken by our department, as it draws on analysis and expertise across the whole of government.”
:: November 27: Mr Davis provides a dossier of around 850 pages to the Exiting the European Union Committee but admits that sensitive information has been withheld.

In a letter to the committee he said: “Since the start of this process I have been clear that there are not, nor have there ever been, a series of discrete impact assessments arising out of our analysis of the 58 sectors.”
:: November 28: Exiting the European Union Committee chairman Hilary Benn summons Mr Davis to give evidence, warning that his decision to withhold information is “contrary to the instruction given to the Government” by the Commons. He said the committee would “need to consider whether this is potentially a breach of privilege”.
:: December 6: Giving evidence to the committee, Mr Davis confirms that no sectoral impact assessments have been undertaken, as it was believed their usefulness would be “near zero”, given the scale of change which Brexit will cause to the UK economy.
