EU 'open but unconvinced' by Boris Johnson's Brexit plan

The European Union is 'open but not convinced' by Boris Johnson's new proposals for a Brexit deal with the EU, the president of the European Council said.

Donald Tusk was among several leading EU voices to express doubt over Boris Johnson's withdrawal agreement plan.

The plan would keep Northern Ireland in the EU single market for goods but see it leave the customs union.

But what happens to the border between Northern Ireland and Ireland remains a central sticking point.

Irish PM Leo Varadkar said the new plans for the withdrawal agreement were welcome, but "fall short in a number of aspects".

It comes as Johnson's Europe adviser, David Frost, is to hold another round of talks in Brussels in a bid to break the Brexit deadlock.

The EU's chief negotiator, Michel Barnier, has told European diplomats he still has plenty of questions about the British proposal to replace the backstop - the measure designed to prevent a hard border on the island of Ireland after Brexit.

He has said he will be in a better position to judge possible future negotiations with the UK once he has spoken to Frost.

On Thursday, Johnson said he had made a "genuine attempt to bridge the chasm" with EU officials before time runs out to reach a deal for the 31 October deadline for the UK to leave the EU.

The UK government says it is aiming to reach a final agreement at an EU summit on 17 October.

EU leaders face a delicate political dance, uncertain if Johnson is open for deeper negotiations or is focusing his attention on a possible election campaign.

Meanwhile, Scotland's highest civil court is to consider whether Johnson could be jailed if he ignores legislation aimed at preventing no-deal.

The so-called Benn Act requires the government to ask the EU for an extension to the Brexit deadline if it fails to either pass a deal in Parliament or get MPs to approve no-deal, by 19 October.

However, Johnson has repeatedly insisted he would not ask for a delay as the law requires him to, describing the legislation as a "surrender bill".

EU negotiators say they have already identified problems with the plans, including the continuing failure to avoid a hard border on the island of Ireland and the threat to the single market.

Donald Tusk reacted in a tweet, after speaking to Taoiseach Leo Varadkar, who is seen as key to agreeing to a withdrawal deal.

For his part, Varadkar voiced concerns over the customs proposals, questioning how Northern Ireland and Ireland could operate under different customs systems without the need for physical checkpoints.

He also questioned the plan to give Northern Ireland's Assembly a veto over entering into a "regulatory zone" with the EU, without the involvement of Ireland or the EU.

The UK has made some progress but "further work is needed", European Commission chief Jean-Claude Juncker said.

Accepting the current proposals would not meet the objectives of the backstop including preventing a hard border, he added.

Meanwhile, the European parliament's Brexit co-ordinator, Guy Verhofstadt, called the plans "unworkable".

In an interview with the BBC, Verhofstadt said the plan represented "a repackaging of old ideas".

Earlier, the European parliament's Brexit committee said the plan didn't match "even remotely" what had already been agreed.
