The euro fell to a four-week low against the British pound on Thursday, with the single currency weighed down by Greek concerns which also prompted some safe-haven inflows into sterling, traders said.
Greek two-year yields rose over 100 basis points after Standard & Poor's downgraded the country and Germany's finance minister said on Wednesday there was little chance of the euro zone reaching a deal with cash-strapped Athens next week.
The euro fell to 71.65 pence, down 0.45 percent on the day. The single currency was also down half a percent against the dollar at $1.0631.
