The Monarchy

In Britain, there are people believe that it should be keep The British Monarchy, because they consider them as a symbol of their country. On the other hand there are others do not.
In my opinion it does not necessary to keep The Monarchy. Honestly before i thought The Queen has a power to control the country, but the fact that has been discovered is The Queen does not have any power that will be consider. For that reason it is not important to keep The Monarchy. Also i can not see any benefits from having a royal family in UK, because the system in UK is controlled by the government, which is represented by PM and MPs.
