Finally, Alexander Boris de Pfeffel or commonly known as Boris Johnson, is officially becoming the new British Prime Minister, replacing Theresia May who resigned as British prime minister due to the Brexit impasse on 7 June. Some people say May was forced to resign because she failed to deliver her Brexit plan to leave the European Union. In an internal vote in the Conservative Party, Johnson won 92,153 votes and outperformed his rival, Jeremy Hunt, who is currently serving as British Foreign Minister, who won 46,656 votes. President of the Republic of Indonesia Joko Widodo expressed his congratulations to Boris Johnson through his twitter account, @jokowi on Thursday (25/7). He hopes that there will be an increase in bilateral relations between Indonesia and Britain and can strengthen relations between the two countries. United States President Donald Trump also expressed his congratulations and convinced that Boris Johnson would achieve the best results in his position as Prime Minister. A different response was seen from the congratulations expressed by Iranian Foreign Minister, Mohammad Javad Zarif following the election of Boris Johnson in the internal vote of the British ruling party, the Conservative Party. Minister Zarif said that Iran is not seeking confrontation; Iran wants normal relations on the basis of mutual respect. This is related to Iran's insistence that Britain should release tanker after the British authorities seized an Iranian tanker off the coast of Gibraltar on suspicion of bringing oil to Syria. Minister Zarif accused the British move of being influenced by US President Donald Trump. Meanwhile, the sound of worries was read in the congratulations delivered by European Commission Chairperson, Ursula von der Leyen who said there would be tough times awaiting Britain and the European Commission. In addition, the EU negotiator for Brexit, Michel Barnier also expressed the same concern. If Boris Johnson officially took office, his party would facilitate the ratification of the Exit Agreement and achieve true Brexit. Until now, the British parliament has rejected the Brexit Agreement. Britain should leave the European Union on March 29, 2019. However, this was rejected three times by members of the British parliament. Brexit was later extended to April 12, 2019 and eventually extended again until October 31, 2019. This could be even faster. In this position, Boris Johnson's political attitude triggers controversy. He promised to bring Britain out of the European Union (Brexit) until October 31, the deadline set by the European Union, whatever the way is. Several times, PM Boris Johnson emphasized that he would decide Brexit, both with and without agreement with the European Union. The statement sparked a fierce controversy. Because various economic institutions in the UK, including the Central Bank, have warned that Brexit without an agreement will cause the UK to suffer from a prolonged economic recession. Finally, to answer various predictions and worries, we just have to wait and see what will be done by the new British Prime Minister, Boris Johnson. Congratulation on leading the UK.
