As Britain's main opposition leader, Jeremy Corbyn, jumps into the Brexit debate, opinion polls hint at an evenly divided electorate - while forex traders warn of a massive fall in the British pound should the UK leave the EU. Grace Pascoe reports.
With the UK's vote on EU membership this month ... It's a big day for both the INS and the OUTS. Both sides pulling out the stops, including the UK's main opposition leader. British workers, he says, better off with the EU. (SOUNDBITE) (English) LABOUR LEADER AND VOTE REMAIN SUPPORTER, JEREMY CORBYN, SAYING: "It means workers throughout Europe have decent rights at work, it means it is harder to undercut terms and conditions." Prime minister David Cameron also in focus as he braces for a televised Q and A session. But armed with new ammunition from the OECD - they warn of a sharp slowdown in UK growth in the case of a Brexit. Sterling too could suffer - a forex survey predicting the pound could lose a tenth of its value if Britain leaves. The currency already vulnerable after recent figures put net migration in 2015 at the second highest on record. That helping the Leave camp nudge a three point lead in two polls earlier this week. (SOUNDBITE) (English) PANMURE GORDON CHIEF ECONOMIST, SIMON FRENCH, SAYING: "That dynamic around migration is hitting home with floating voters and therefore sterling will come under pressure which has become almost a pure trade based on each poll we see." The latest poll, by YouGov, shows an even split between the INS and OUTS. With June 23rd fast approaching it is still all to play for. The Leave camp still hoping the cookie will crumble in their favour.
