Based on my information, I believe that the higher authorities that would choose the prime ministers would actually be the "house of commons". Going back a few years, many of the "house of commons" actually did not have the responsibility in order to do this, but then, the government figured that it would be better if they were to handle on this responsibility.
The 13 colonies opposed these acts because the colonies were being taxed without representation meaning that the colonies usually made their own taxed untill the Britsh stated tax acts without giving the colonies any say on if they wanted them so the colonies protest these acts fearing that the colonies were going to get pushed around by the Britsh
The president 2019: Donald Trump
Have rights under tax laws. Britain kept added more tax laws when the colonists has no say or no representation. They thought this was un fair so they established their own representatives. I think this is right
