Wrong
It is sad how socially acceptable absolute ignorance on quesions of how the EU works has become in the UK. You can post obviously wrong statements like the one above and get a lot of confirmation and not a single person would correct the factual errors.
The EP elects the EU commission based on proposals from the Council but most importantly can fire the Commission any time it sees fit. It has a veto power over all budgetary questions of the EU. For all laws which fall under the ordinary legislative procedure (the vast majority of them) the European Parliament is the equal legislator together with the other legislative chamber, the Council (of ministers, which is quite comparable to the German Bundesrat). That means it has the same powers to amend and to scrap/block it alltogether. The few remaining other legaslative areas of the EU are the not very integrated ones where every member states maintains its veto power on its own. Furthermore Parliament has a veto on all international treaties the EU may negotiate. It was the parliament which killed ACTA after civil society across Europe successfully campagined against it (for better or worse, I think for the better) and the parliament will also have the power to kill TTIP if it chooses so.
Put all of this together and the European Parliament is in fact more powerful than some national legislatures which might do de facto no more than rubber stamping governmental decisions. You hate it, you like it, or you don't care, but to say MEPs have no say in almost anything is either complete ignorance on EU issues or deliberate misinformation.
