Boris Johnson has 1
Anti-Rhine said he and French President Emmanuel Macron agreed that Britain should submit the proposals in writing by the end of September, adding, if not, "then it's over."
Finland is currently the rotating president of the EU.  A Downing Street source said: "We will continue the negotiations and make proposals at the right time."
Mr Johnson said the deal was possible at a crucial summit of EU leaders on October 17, but he insisted Brexit would happen by the 31 October deadline, even if the agreement was not agreed.

The UK government says talks with the EU have progressed since Mr. Johnson at No. 10 in July.
He stated that he presented "a number of proposals" as alternatives to the Irish border backstop – a policy aimed at preventing a hard border returning to Ireland and a key turning point in Brexit by former Prime Minister Theresa May
But Mr Johnson has repeatedly refused to reveal details of the proposals in interviews, saying he did not want to negotiate publicly.
The EU continues to criticize the United Kingdom for failing to submit written plans.
Earlier, the President of the European Commission, Jean-Claude Juncker, said Monday's meeting was "constructive".  But he said, until proposals were made, "I cannot tell you, looking straight into your eyes, that real progress has been made."

Mr Rin spoke to reporters after meeting with the French president in Paris on Wednesday.
He said, "We both agreed that now was the time for Boris Johnson to submit his own written proposals – if they existed.
"If no proposals are received by the end of September, then everything is over." agreed with other EU countries.
"A radically different deal"
Commons leader Jacob Rees-Mog insisted that the prime minister was about to conclude a "radically different" deal for Brexit to secure leaving the UK on 31 October.
He told an event in the Telegraph that in order to achieve such a result, the government had to "listen very carefully to what the DUP was saying."
On Wednesday, DUP leader Arlene Foster told business leaders in Dublin that he wanted a Brexit solution that did not affect the constitutional position of Northern Ireland.
Ms Foster – whose party support had until recently given the Conservatives a majority in parliament – stated that a Brexit deal "would not be reached that included a backlash – whether for the UK or Northern Ireland".
The whole of the UK had to leave the customs union and the single market, she said.
But she added that the DUP was prepared to "consider Northern Ireland-specific decisions reached with the support and consent of the representatives of the people of Northern Ireland".
This is because the legal battle to suspend the UK Parliament is to enter the Supreme Court on the third day later.
The United Kingdom Government argues that the decision to propose Parliament is a political issue and not for the courts to "design a set of rules" around it.
But campaigns say the move was used "for the wrong purpose" – to stop MPs from reviewing Mr Johnson's plans during Brexit on October 31st.
The Prime Minister prophesied Parliament earlier this month for five weeks, with MPs not due back until October 14th.
Mr Rees-Mog, who traveled to Balmoral to seek the Queen's approval of the move, said it was "foolishness" to suggest she was misled by the decision.
