David Cameron's resignation may be an indication that he is not confident of this capabilities to fully lead this transition. It does not , however, mean that he cannot and will not help implement the process. In recent press conferences, Cameron has pledged that he will do whatever he can to help his country.
The British Prime Minister David Cameron should not stay as PM after the "Brexit" vote where Britain decided to leave the EU. He did not support the vote, so he was right to say that Britain deserves a leader who will more solidly guide the country through this controversial time.
David Cameron resigned as Britain's PM after Brexit vote. He should not stay to help implement the process because he never supported Brexit. However, his decision would definitely affect Britain's future, because, as Prime Minister he has done quite a few things and today Britain boasts of a strong economy.
David Cameron was in favor of the United Kingdom remaining in the European Union. Therefore, when the U.K. voted to leave it was no surprise that Cameron would resign as Britain's prime minister. Cameron would not have much of a mandate to remain on and oversea a process that he was opposed to taking place in the first place. In short, David Cameron should not be involved in the process of the U.K. leaving the EU because he was opposed to Britain leaving.
