The FTSE-100 closed the day down 3.69 points at 5946.25. European counterparts were equally unsure what to make of the geopolitical movements, with the German Dax flat and French CAC down 0.34%.

Connor Campbell, financial analyst at SpreadEx, explained that the moves in the US indicate the president is not anti-stimulus, but a politician – pointing out Mr Trump promised a package after the election.
He said: "At the moment it's a lot of hot air and may be setting up the markets for disappointment down the line. Nevertheless, US investors seem to be buying Trump's pronouncements."
