Cameron takes over the premiership of the government and the party temporarily until the general party’s congress in October.
The party elections are scheduled to end by September 9, with the winner taking over at the party’s congress next month.
The new Conservative leader assumes the responsibility of heading the government, given that the party has a sufficient majority in the House of Commons until the next parliamentary elections scheduled for 2020, if no early elections are held.
Among the most prominent candidates are Teresa May, the Home Secretary, who has the most supportive MPs, Michael Goff and Stephen Crab William Fox, as well as Andrea Ledsom, the Energy Secretary, who has received the support of former London Mayor Boris Johnson.
The party’s 330 members in the House of Commons will vote in two phases, with each deputy giving his vote to one of the candidates, regardless of the number. This round will take place on Tuesday morning and its results will be announced before the end of the day.
In the second stage, the deputies will choose the party leader and prime minister from among the top two candidates, according to the results of the first round.
The candidates spoke to the Conservative party MPs Monday in an attempt to explain their priorities and how to manage party and country affairs in the coming period, foremost of which is how to manage the expected negotiations with the European Union for secession.
In her statement to deputies, Theresa May confirmed that she would use the position of British residents on the European Union as part of the negotiating papers with the European Union.
While Goff and Ladsum said that the position of European nationals residing in Britain is not an area of negotiation, recognizing their right to reside and work in Britain.
