The early jubilance shown by British Prime Minister Boris Johnson after securing what he said was the best Brexit deal from Brussels has faded away as it seems it is unlikely to pass the test at the British parliament.

With key allies from Northern Ireland, such as Democratic Unionist Party vehemently opposing the deal, it is unlikely that the government, which is already a minority in the parliament could make the cut.

Here is a look at what could be the possible fate of Britain and the Brexit deal if it is not passed in the parliament.

If the bill gets passed in the parliament

If in a highly unlikely scenario the bill is passed, then the UK will officially leave the European Union on October 31. Even then the transition will not be sudden in order to avoid confusions such as border issue between Northern Ireland and the Republic of Ireland. This transitional period is expected to last up to a year.

If the bill is not passed

There are mainly two scenarios that are expected to happen if such a situation arises. Firstly, as in the case of the previous Theresa May government, Johnson would be compelled to resign leading to the creation of a caretaker government. Which likely will ask the EU for another extension. In simple words, it will just lead to the repetition of the existing political drama, albeit with different lead players.

However, if Johnson decides to not resign, things could get even complicated. The leader, famous for his anti-EU stance since his days as a journalist could decide against seeking an extension. This, in turn, could lead to attempts to carry out Brexit without any terms leading to severe complications including legal hurdles.
