Q&A / Others / What does an MEP do? The UK legally had to take part in the EU elections because Parliament had not yet passed a Withdrawal Agreement. What will your MEP do? Here’s more: MEPs cannot introduce legislation since this is done by the Commission but they can propose legislation. A huge role is in the scrutinising and amending of legislation. MEPs can also outright reject any proposed legislation. MEPs represent their constituents and their interests in the European parliament. These interests are often reflected at the stage when they are amending legislation to make sure that a law can work for that MEP's region. MEPs spend about 1/3 of their time in their constituency. They attend meetings and events there as well as working on constituency enquiries via telephone and email. One of the biggest roles that an MEP has is to be part of the budget setting process. They take a look at the proposed annual EU budget and try to secure support for greater allocation of money in certain areas. MEPs meet with experts from different industries, such as people from think tanks, businesses and NGOs to ensure that they are well informed when it comes to shaping laws.
