One week ago (June 7, 2019), British Prime Minister, Theresa May announced her resignation from the position of Chairwoman of the Conservative Party. That means that the position of the Prime Minister of England is automatically vacant, because the leader of the majority party or coalition of parties winning the general election occupies the position of the prime minister. Theresa May still sits as Prime Minister until the election of a Conservative Party Chairperson. May resigned because several times her efforts convinced the parliament that the UK left the European Union with an agreement not to reach the expected support.May's resignation opens opportunities for several party chairmen candidates such as Boris Johnson, and Jeremy Hunt who is currently serving as Minister of Foreign Affairs or Michael Gove who is serving as minister of the Environment. Boris Johnson is a supporter of Hard Brexit, which is to leave the European Union without a deal. Others may compromise with Brexit. This is a challenge if Boris Johnson wins. On October 31, this means that the British will leave. Whereas if the conservative leader is more inclined to agreement, the United Kingdom must renegotiate with the European Union. But that does not mean the problem has been resolved, because the European Union also seems not to open new opportunity to the agreement. Why? Because at least, Theresa May has tried to build an agreement with the EU, but instead of having no support from the British parliament. In the parliament, there are three camps. Some Conservative members support Hard Brexit. Labor supports Brexit with an agreement. There are some Conservative members supporting Brexit with an agreement. This is what caused May not to get the majority support.Now, the problem is entirely dependent on the British parliament. They will actually determine who the next British Prime Minister is. The chosen Prime Minister means Brexit with or without agreement.
