CEOs across a host of sectors have backed Britain to prosper as the country prepares to leave the EU at 11pm tonight. Bankers in the City are optimistic that Brexit could lead to a £100m surge in deal making. Dwayne Lysaght, M&A co-head of Europe, the Middle East and Africa at JP Morgan, said: “Buyout funds still have a lot of money to put to work and leverage markets are very strong. There is still quite a bit of distance to cover with our EU partners, but investors are done waiting.” City chiefs have also backed the Square Mile to retain its global pre-eminence although a battle awaits with European regulators. Catherine McGuinness, policy chairman at the City of London Corporation, said the City “will continue to lead the world” after Brexit as a centre of global finance.
