What would be the main reason to call for an election, to boost the majority of seats in the house of commons to allow bills an easier ride, however, on the 8-June-2017 Theresa May found out that it was not that easy.
If Boris Johnson asked parliament on 19 September for an election on 24 October, the last Thursday before the expiry of the Brexit extension, it could happen if two-thirds of MPs vote for it.
The opposition could force a general election only by bringing down Johnson’s government. Corbyn would have to pass a motion of no confidence and wait for 14 days. That process would normally have needed to start on 25 July, the last day before the summer recess, by tabling the motion of no confidence, to be voted on 3 September, the day parliament reconvenes after the summer recess.
Jeremy Corbyn has said Labour is ready to fight an election campaign against Boris Johnson but refused to express a preference between leaving with a Labour-negotiated deal or staying in the EU. The Labour leader said he was “absolutely” gearing up for an election, with a summer campaign plan, new policies on a green industrial revolution and candidates already selected in almost all marginal seats.
When this was first mentioned after the announcement of Boris Johnson as Prime Minister, I did not think it would be a good idea and would detract from the business of Brexit. However, considering the past few days since then it now appears that the knives are out for Jeremy Corbyn and therefore I have changed my mind as I believe that Boris Johnson would defeat Jeremy Corbyn a lot easier in an election than his replacement, whoever they may be.
