The City of London wants the Conservative Party to provide more clarity over the future of international workers in the UK after Brexit, a particularly important issue for the country's financial services sector where almost a third of staff are hail from overseas.

Catherine McGuinness, policy chairman at the City of London Corporation, said in a statement: "The ‘London is open’ tagline will wear thin if politicians don’t provide answers for our international workforce. This uncertainty also affects workers up and down the country."
