Earlier today, sterling rose to as high as $1.4285 against the weakening dollar. At the time of writing, the pound was up 0.15 per cent to $1.4163.
David Madden, market analyst at CMC Markets, said: "The downward trend in the US dollar is showing no signs of letting up, and the pound is being propped up by it.
"Sterling has slipped since the morning, but the upward trend is still in place so we could see new buyers enter the market."
Madden said the rally across European stocks felt "lacklustre".
"Even though equities are in positive territory the level of enthusiasm isn’t anything special."
