Ahead of Britain's exit from the European Union at the end of this month, it is unclear how the UK intends to manage this separation.

Here are five outstanding questions:

- What possible agreement?
British Prime Minister Boris Johnson does not want "backstop", the safety net provided for in the agreement reached by former Prime Minister Theresa May. The aim of this mechanism is to avoid the restoration of the border between the Northern Ireland of the United Kingdom and the European Union member Republic of Ireland in the south, preserving the 1998 peace accords and also the single European market.

In its current version, this mechanism, which will be adopted at the last minute, provides for the creation of a “single customs zone” involving the European Union and the United Kingdom, which Brexit supporters consider to keep their country in the lap of Brussels indefinitely. Consequently, other solutions should be found, including customs centers several kilometers from the border.

Dublin saw this as a new frontier. The other solution is control points in the Sea of ​​Ireland, but this is unthinkable for many conservatives because it would compromise the sovereignty of the United Kingdom.

- Does any new agreement receive support?
British lawmakers have rejected three times the previous agreement, which Teresa May barely negotiated with the EU, and if Johnson manages to reach a new deal, he will have only a few days to push parliament to pass it. .

Tensions between the prime minister and lawmakers peaked last week after the Supreme Court overturned Johnson's decision to suspend parliament.

- Can Brexit be postponed?
Brexit, originally scheduled for March 29, has been postponed twice because of a lack of majority in parliament over how to secede.

A law passed on September 10 compels Johnson to ask the EU to postpone Brexit's three-month deadline if no agreement is reached at the upcoming EU summit on 17 and 18 of this month. He will not ask for this deferment.

Such a delay would need the approval of the 27 EU member states that want to have a clear idea of ​​the next steps.

- Can elections be organized?
In light of the ongoing crisis in the country and the absence of a government majority, the prospect of early elections seems inevitable in the coming weeks and months, and all parties are preparing for them strongly.

So far, the Labor opposition has been elusive, saying it is waiting for the Brexit date to be postponed, and in the current chaotic situation it is not certain that a clear majority will emerge after the elections.

- Can Brexit be avoided?
According to the opposition, Brexit is not inevitable, and the Labor Party promises that if it wins the elections there will be a second referendum in which the choice between a renegotiated agreement with the EU or a staying in the bloc will be held.

The Liberal Democrats and Scottish separatists want to "prevent Brexit," but time is running out to change course.
