BORIS Johnson was rebuffed in Paris yesterday, with French President Emmanuel Macron rejecting his plea to renegotiate Brexit.

While he didn’t slam the door shut on the Prime Minister, and even hinted at the possibility of changes to the Withdrawal Agreement, he made clear that the Irish backstop was “indispensable”.

The meeting between Macron and Johnson came as the leaders of all the opposition parties in the Commons agreed to meet next week ahead of Parliament’s return, in a bid to try and find a way to kibosh a No-Deal Brexit.

Chances of a deal acceptable to a majority of MPs being remain slim.

In a joint press conference at the Elysee, Macron said there would be no “reshuffling” of the Withdrawal Agreement, but he added: “We should all together be able to find something smart within 30 days if there is goodwill on both sides.”

“We need to try to have a useful month.”

He added: “We will not find a new Withdrawal Agreement within 30 days that will be very different from the existing one”

The backstop – a safety net to prevent a hard border on the island of Ireland – was, he added, a “genuine, indispensable guarantees” to preserve stability.

The Tory leader insisted alternatives to the backstop could still be found.

“[German Chancellor Angela Merkel] said if we can do this in two years then we can do this in 30 days and I admire that ‘can-do’ spirit that she seemed to have and I think she is right,” Johnson said.

“I think that the technical solutions are readily available and they have been discussed at great length. You can have trusted-trader schemes, you can have electronic pre-clearing for goods moving across the border and I just want to repeat one crucial thing: under no circumstances will the UK be putting checks at the frontier.

“We don’t think it is necessary from the point of view of the EU to do that to protect the integrity of the single market, we think there are other ways of doing that. We have got, I think, adequate time to do it — let’s get on and do it.”

He added: “Let’s get Brexit done, let’s get it done sensibly and pragmatically and in the interests of both sides and let’s not wait until 31 October. Let’s get on now in deepening and intensifying the friendship and partnership between us.

“When you look at the border with Northern Ireland ... under no circumstances will the UK Government be instituting, imposing checks or controls of any kind at that border. We think there are ways of protecting the integrity of the single market and allowing the UK to exit from the EU, all and entire and perfect as it were.”

However, the German chancellor tried to move away from the the 30-day deadline saying it was only “an allegory for being able to do it in a short period of time”.

“It is not about 30 days. The 30 days were meant as an example to highlight the fact that we need to achieve it in a short time.”

All three leaders will be in Biarritz in France this weekend at the G7 summit of world leaders along with Donald Tusk, the president of the European Council.

In London, the SNP, LibDems Change UK, Plaid Cymru and the Green Party have all agreed to attend a meeting organised by Jeremy Corbyn.

In a tweet, Jo Swinson, who last week said she couldn’t work in a government with the Labour leader, said: “I look forward to discussing how we can stop the disastrous consequences of no-deal and will be asking Jeremy Corbyn if he is open to all options to prevent it. We have to focus on plans that have a chance of success.”

Plaid Cymru’s Commons leader, Liz Saville-Roberts, said she would meet Corbyn, but added: “In this crisis, policy comes before personality. If Corbyn fails to offer workable plan, others must be given the opportunity.”

Former Tory MP Nick Boles, however, rejected the invitation.
