In the UK legislative and executive power is normally merged by the government whips maintaining control, and the parliament has the power to (dis)approve. Parliament can attempt some amendments, but they must be in scope, and again under normal circumstances the amendment won't pass without support of the government. MEPs can also amend bills coming from the commission, so very similar to the UK system. Of course we live in interesting times, with a minority government, a fractured party, and parliament last night made a move that hasn't been done for over 100 years. Even last night all parliament did was gain control over it's own timetable. Still parliament can't effectively pass any laws on it's own -- take the Voyeurism (Offences) #2 bill. An MP had attempted to introduce this, but 1 MP had objected, and thus it couldn't be passed. Instead the government introduced it.
