British MPs will try to legislate in the urgency this week to try to prevent a "no deal", an exit from the United Kingdom of the European Union (EU) without agreement. And this before the closure of Parliament, from September 9 to October 14, decided by the government of Boris Johnson. On the brink of an eventful week in the British Parliament, here are the possible Brexit scenarios:

A Brexit without agreement

London and Brussels can not reach an agreement and the UK leaves the EU without a withdrawal agreement on 31 October.

Feared by economic circles, such a sudden exit raises fears of tariffs being restored as well as shortages of food products, gasoline and medicines. The government began this weekend a vast information campaign encouraging businesses and individuals to "prepare for Brexit".

New report

British MPs vote a law compelling the government to seek a further postponement of the date of Brexit, to avoid a "no deal".

Opposition politicians could benefit from the support of rebel conservatives to vote for such a text, even though Boris Johnson has threatened to expel the Tories who would be tempted to do so.

In any case, the deputies have only a few days to legislate before Parliament is suspended. The suspension, decided by Boris Johnson, has provoked a wave of indignation from the opponents of a "no deal", who see it as an attempt to gag them.

Then it would be necessary for the government to comply with the will of Parliament. The minister responsible for preparations for an exit without agreement, Michael Gove, refused to say whether the government would submit to such legislation, fueling fears of a passage in force Boris Johnson.

Early elections

The opposition, led by Labor, could pass a vote of no confidence to bring down the government, whose absolute majority in the House of Commons is only one seat.

However, nothing prevents Boris Johnson to decide that the vote takes place after October 31, after the exit of the United Kingdom from the European Union. It could also trigger the organization of early elections in hopes of strengthening its majority. An option he has nevertheless ruled out Monday, according to his spokesman.

According to former Conservative Justice Minister David Gauke, a Conservative opposed to an exit without agreement, the government's strategy is to "lose this week" in Parliament "and then call legislative elections by eliminating those of us who do not are not against Brexit, not [those] against a departure from the European Union, but [those] who consider that we should leave with an agreement ".

Brexit with agreement

London and Brussels manage to reach an agreement and agree on the crucial issue of the backstop, the Irish safety net. This clause, which aims to prevent a return to a physical boundary between the British province of Northern Ireland and the Republic of Ireland, is at the heart of London's discontent.

But EU negotiator Michel Barnier has ruled Sunday, September 1 to renegotiate the backstop that Boris Johnson wants to see disappear.
