During the evidence session, with the committee shadowing his Department for Exiting the European Union, Mr Davis also:
* Said it was probably right that holidaying Britons will lose EHIC cards, which provide free or subsidized healthcare across the EU, but added: I have not looked at that one.
* Admitted he did not know the implications of leaving with no deal on the transfer of personal data, which is crucial issue for the booming tech industry.
* Acknowledged UK producers of dairy and meat would face tariffs of up to 40 per cent under World Trade Organisation (WTO) rules the numbers in agriculture are high.
* Described the argument that the UK could walk away without paying a penny to the EU, if no deal is reached, as interesting a very good start in this exercise.
* Said he expected Northern Ireland would end up with a very light border, not a hard border with the Republic.
* Said he assumed the Open Skies agreement which has slashed airfares across the EU - will be lost, although he would fight for a successor.
* Confirmed financial services firms are poised to lose passporting rights to trade in the EU, saying: I would expect that to be the case, thats an area of uncertainty.
