The European Commission is adamant that, as they stand, "the United Kingdom proposals do not provide a basis for concluding an agreement".
Johnson on Saturday called his plan "a practical compromise that gives ground where necessary" but has also previously suggested it was a broad "landing zone" - which to Brussels suggests he might yet budge on issues it finds unacceptable.
U.K. Prime Minister Boris Johnson is prepared to challenge Queen Elizabeth II to dismiss him rather than resign as he attempts to push through Brexit by the October 31 deadline, the Sunday Times reported, citing senior aides.
Writing in the Sun on Sunday, he added: "If we're to leave with a deal, we now need the European Union to jump over from its side and join us there, showing its own willingness to do a deal that the UK Parliament can support".
After pointing out this Sunday that his proposal represents a decisive step on the part of London, the Premier said that it is now the turn of the European Union to act, and show that it is interested in reaching an agreement that will gain the support of the British Parliament.
Yet if he bends on them, he risks losing tenuous support in the United Kingdom parliament to maybe pass a Brexit deal, reliant on the ten DUP MPs and hard-core Brexit MPs in his Conservative Party.
He claimed MPs from "every wing of the Conservative Party", Northern Ireland's Democratic Unionist Party and from Labour have said "our proposed deal looks like one they can get behind".
"They should be under no illusions or misapprehensions", he added.
This mindset was echoed by Mr Johnson's Brexit secretary Stephen Barclay who wrote in the Sunday Telegraph that the country was "approaching the moment of truth".
"There will be no more dither or delay. The problem is at the moment we don't have a deal", she said.
"We are ready for no-deal, even if we don't desire it", he said. "It would bring disruption for us, and disruption for the European Union".
He said: "I think a deal is still possible..."
Ireland's leader Leo Varadkar said Saturday there is "plenty of time" to put forward alternatives and he was trying to arrange a meeting with Johnson next week, Irish broadcaster RTE reported. Although Johnson repeats to the full that the United Kingdom will leave the European Union on October 31, with or without agreement, the British Parliament passed a law in early September to force it to request a postponement of the exit, in case of not signing a new pact before October 19.
Brussels reportedly balked at Britain's request to keep initial discussions on the proposals going through the weekend. Rutte writes on Twitter that he still has many questions about Johnson's proposal, after they had spoken to each other by telephone.
If thwarted, Mr Johnson's best bet may lie with early elections.
Mr Johnson's insistence that Britain will leave at the end of the month comes after Scotland's highest civil court heard from UK Government lawyers that Mr Johnson accepts he must send a letter requesting a delay to Brexit beyond the Halloween deadline if no deal is agreed with Parliament by October 19.
