If the Bank of England raises interest rate, or hints that it will, the pound will rise further. The ECB kept theirs on hold today. That said, apparently the latest rise in the value of the pound has all been about the election on June 8 and the likelihood that the Tories will gain many more seats, so watch the polls between now and then as they could affect the pound - Tories strong, pound strong; Tories weak, pound weak.
