The pound dropped against the dollar earlier this week amidst uncertainty surrounding Britain’s membership of the EU.
The Mayor of London, Boris Johnson, has joined the campaign to leave the EU, which has increased concern that the referendum in June this year could be marginal.
In contrast however the pound was little changed against the euro, which itself has been weakened by a fall in German exports during the fourth quarter.
Mark Carney, Bank of England governor, noted that there had been movements in sterling since the weekend, when it was announced that the referendum would take place on 23 June.
