Sterling on the up after euro hit by German inflation figures
The pound pushed higher on Thursday, boosted by investor relief in the wake of Article 50, as well as a weaker euro following disappointing German inflation figures.
Sterling surged 0.8% to 1.164 against the euro, which wobbled after German harmonised consumer price inflation came in below economist expectations at 1.5%, knocking hopes the European Central Bank might trim its stimulus programme.
The UK currency also gained some ground against the US dollar, rising 0.4% to 1.248.
It came as investors breathed a sigh of relief after seeing little fallout from the trigger of Article 50 a day earlier.
Connor Campbell, a financial analyst at SpreadEx, said: "With the triggering of Article 50 failing to spark a major catastrophe, beyond, you know, Brexit itself, it appears investors are willing to allow the pound to return to the highs it saw at the start of the week."
The stronger pound took its toll on the FTSE 100, which ended the day relatively flat, down 4.2 points at 7,369.52.
