European shares fell for the first time in four sessions on Tuesday, as uncertainty over Britain’s chaotic exit from the European Union and continuing trade tensions between the United States and China weighed on sentiment.

British lawmakers will decide on Tuesday whether to move Britain one step closer to a snap election when they vote on the first stage of their plan to block Prime Minister Boris Johnson from pursuing a no-deal Brexit.

That sent the pound down to its lowest since January 2017, helping the export-laden blue chip index .FTSE outperform other European markets with a 0.14% rise.

The pan-European STOXX 600 index , however, was down 0.26% by 0715 GMT.
