Its anyones guess which way the sterling will go v the euro however common opinion is that sterling will remain under pressure with a number of interest rate drops forecast in the UK and ECB maintaining a strong stance against inflation.
If you accept that sterling is going to get worse you should pull it out, convery to euro and invest in my opinion. I am sure there are many more opinions on the forum though but Im sure few could argue,
If you are sending money back from the UK price around, the UK banks are not the best way to do it, check xetrade or currency.ie for better rates
