The pound rose tentatively against the dollar on Friday after an uneventful week for the currency, despite the extension to the Brexit deadline.
Sterling was up 0.27% at 1.309 US dollars, boosted by apparent cooperation between the major parties over Brexit.
Connor Campbell, financial analyst at Spreadex, said: “Shadow chancellor John McDonnell’s claim that talks between Labour and the Tories have so far been ‘positive’ and ‘constructive’ did what the Halloween Brexit delay couldn’t and gave the pound a boost on Friday.”
But the currency was down 0.1% versus the euro at 1.159.
The pound’s gains held back the FTSE 100, which climbed 19.11 points, or 0.26%, to 7,437.06.
The French Cac was up 0.3% and the German Dax was down 0.02%.
Michael Hewson, chief market analyst at CMC Markets UK, said: “Markets in Europe have built on last week’s strong gains after this morning’s Chinese trade data saw exports rise to a five month high.
“While some of this jump may well be as a result of a rebound after Chinese New Year, it also suggests that despite concerns about an economic slowdown, that external demand in the global economy, while weaker than a year ago, still remains sufficient to sustain further economic expansion.”
