The Parliament is directly elected by the people of Europe once every five years. This gives the 751 MEPs a unique and powerful voice.
The Parliament legislates (alongside the Council), provides oversight of the Commission and, perhaps most significantly, approves the entire EU budget. The Parliament also reserves the right to veto trade deals, as occurred in the case of Anti–Counterfeiting Trade Agreement (ACTA). This power will be of huge significance in relation to the withdrawal agreement for the UK and any future free trade agreement between the EU and the UK. At the moment Scotland has six MEPs. Unless Brexit can be prevented these will be last to represent Scotland.
