Paul Blomfield, a shadow Brexit minister said: "This letter exposes the deep divisions that run through the heart of this Tory government". A new British party inspired by French President Emmanuel Macron's movement say definitely NO. This would last until the complexities of its new scenario are fully thrashed out.
Meanwhile, a bus emblazoned with the alleged economic cost of quitting the bloc began a tour of the country on Wednesday.
"There have been a range of views on Brexit within the group from the beginning", he said.
Another proposed change in the United Kingdom document is to delete a provision in the EU version of the text which would have prevented the United Kingdom from taking "any action or initiative which is likely to be prejudicial to the [European] Union's interests in the framework of any global organization, agency, conference or forum".
Britain wants to retain close economic ties with the European Union after it leaves the bloc in March 2019, while also becoming free to strike new trade deals around the world.
But Davis' speech, the latest in a series ahead of crucial talks with Brussels on the future trading relationship due to start from April, was immediately criticised. Will there be customs checks and tariffs on goods?

This arrangement will not go down well with hardline Brexiteers and Mrs May will face serious opposition.
The letter published on Wednesday called on Mrs May to ensure that Britain had "full regulatory autonomy" from the European Union as well as being free to negotiate and sign deals with other countries.
Leaders will also discuss new priorities. And as a party founded by London-based professionals, Renew may struggle to connect with voters in less metropolitan, economically struggling regions where support for Brexit is strongest.
"Government must lead on making the public case that while industry recognises broader public concerns over immigration, companies still need access to the skills at all levels which European Union workers now provide and which can not be backfilled easily in the short or medium term", Hackett said. Almost two years on, and with a tired public hearing whispers of the possibility of a second referendum in the air, opponents of Brexit have made a decision to take their own red bus on the road.
"Brexit in the form that it was promised to the British people with 350 million pounds extra per week going to the NHS, it's simply undeliverable, it's not going to happen".
