And yes, I believe the ability to make one's own laws by the law-making body of my own country will make my life better.
Out of interest, why do you think this?
Personally, I don't care whether the laws are made by remote, out of touch, politicians in Westminster, or by remote, out of touch, politicians in Brussels, and I really don't see what difference it makes.
Although, the whole Brexit farce has shown the that Brussels politicians are at least somewhat more competent than the majority of the morons currently sitting in Westminster.
