"Well laws are approved by the Council of Ministers (made up from our nationally elected representatives) and MEPs (our directly elected representatives). The Commission can propose laws and mostly do but they can only come into force if agreed by the other two groups."
In most cases, it's just a rubber stamping exercise. Very little gets rejected that doesn't come back awhile later only this time to pass.
The MEPs are about as much use as a one-legged man at an arse kicking party.
