Yes, the United Kingdom should stay in the European Union. The European Union will not be the same without the United Kingdom and it will not have the same power and influence. Furthermore, the United Kingdom will not be seen as being as cooperative with other European nations if the country leaves the EU.
I think the United Kingdom should stay in the European Union because of the trade benefits the country and its citizens will receive. Leaving the European Union seems like it would do more harm than good and may make the United Kingdom very unstable. The risks seem to outweigh any rewards.
I think that the United Kingdom should leave the European Union. They should never have given up their full independence in the first place to join the EU. Many of the countries in the EU are dealing with falling economies, and the United Kingdom needs to save itself by voting to get out.
The European Union has been a financial mess, which has created significant problems for the United Kingdom. If the people of the UK decide, through a democratic and fair process, that they don't want to be a part of the EU anymore, then they shouldn't have to be. A nation's people have the right to decide if they want political sovereignty.
