Shadow Chancellor John McDonnell has joined Cambridgeshire Euro MP Alex Mayer and local campaigners in Cambridge.
Just as Labour MPs are fighting Tory austerity in the House of Commons, Labour MEPs are fighting for a fairer economy across Europe.
Labour MEPs are pressing for action to ban exploitative zero-hour contracts and enshrining the principle of equal pay for equal work.
Alex Mayer MEP said: “John’s visit has given a real boost to our campaign. For as long as Britain is in the European Union we need British MEPs standing up for the people of Cambridge. I’ll continue to fight for a fairer deal for workers and stand up for the values of internationalism and cooperation that Cambridge people hold dear.”
