The Leave Means Leave co-chair demanded that businesses need certainty and they will not have certainty until Brexit negotiations make progress.
Appearing on Sky News, Mr Tice said: “We should never have allowed for this sequential process to take place. The talks should have been going on 24/7, seven days a week. Not one week in three or four.
“There’s no way in business we would run this process like this. She needs to say, ‘we are going to publish our WTO plans we are going to give confidence to businesses consumers and the public alike in Britain’.
“Unless we get some progress in the next couple of weeks, literally two or three weeks, we are off. Off and leave.
Mr Tice then demanded that the most “crucial” part of walking away from a deal with the EU is that Mrs May demands Britain pays no money from March 19.
The Leave supporter believes Theresa May should be prepared to walk away before the end of November. He said: “Businesses want some action and if we get on with it, it just gives extra months and weeks for businesses to plan.
“To be honest, any sensible well-organised well-run business now is planning on the basis of ‘no deal’, which is absolutely fine as a base case, after all, WTO is what most great countries trade under.
“If it’s good enough for Australia and America and Canada it’s good enough for the UK.”
In a Commons statement, Theresa May admitted that she was preparing for Brexit talks to fail.
In response, President of the EU Council Donald Tusk said that the EU is not working for a ‘no deal’ scenario.
Mr Tusk said: “We are negotiating in good faith, and we still hope that the so-called ‘sufficient progress’ will be possible by December.”
The EU said that Brexit trade talks will not progress until three key issues are resolved – including citizens’ rights, the Northern Ireland and Republic of Ireland border, and the financial settlement.
A resolution was passed in European Parliament to block Brexit trade talks until “sufficient progress” was made on the key issues. Trade talks were originally planned to start at the EU summit this week.
