David Davis has been accused of misleading parliament after he claimed the government had not conducted impact assessments on the economic impact of Brexit - having previously suggested to it had.
Ten Conservative MPs and one DUP MP voted that Davis was not in contempt of parliament, hours after the Brexit secretary said that there had been "no systematic impact assessment" of leaving the EU.
Mr Davis was quizzed by committee chairman Hilary Benn, who said: "Doesn't it strike you as rather odd that the Government undertakes impact assessments of all sorts of things all the time, but on the most fundamental change that we are facing as a country, you've just told us that the Government hasn't undertaken any impact assessments at all on the implications for various parts of the economy?"
Mr Davis replied: "There's nothing...there's no such systematic impact assessments that I'm aware of".More news: Honor 7X Review: Bezel-less smartphone on a budget
After the announcement of the Budget last month, voices across the sector said that Brexit was its biggest concern because of the uncertainty it caused.
Eventually, following complaints, MPs were eventually handed two files containing 850 pages of mainly background "sectoral analyses" of various parts of the economy.
Elaborating under questioning, Davis said that, due to the fact that economic models can often be inaccurate, it was not necessary carry out specific impact assessments on particular sectors of the British economy, due to the fact the UK Government's stated aim is to secure a comprehensive free-trade agreement that would cover the entire British economy.
However in October he suggested impact assessments did exist and that Theresa May had read the "summary outcomes of them" if not every "excruciating detail".
Mr Davis told the committee: "You don't need to do a formal impact assessment to understand that, if there is a regulatory hurdle between your producers and a market, there will be an impact".More news: Why Patagonia Will Sue President Trump Over Utah National Monuments
Labour MP Seema Malhotra called Davis's admission "a dereliction of duty".
Wera Hobhouse, a Lib Dem member of the committee, said it was "unbelievable" that the assessments did not exist. Either way, how is Davis still in his job?'
"I've written to him in my second letter to say I believe the government are in contempt of the House and I know he's been extremely patient and generous with them, but now it has to end and it's quite clear that they are in contempt, so I'm asking him to make a further ruling".
The general secretary of the GMB union, Tim Roache, said ministers had "either. been leading us up the garden path or they're playing fast and loose with people's livelihoods, communities and the economy".More news: Weather: Snow and ice warning for Northern Ireland
