Commenting on the fall in quarterly GDP growth to 0.3%, down from 0.7%, Peter Kyle MP, leading supporter of Open Britain, said:
"These figures underline why Theresa May should not be given a blank cheque to pursue a hard Brexit. Following falling consumer spending and shakier consumer confidence, the post-referendum plunge in the value of the pound is clearly making working people worse off.
"This should be a warning that leaving the Single Market and voluntarily erecting trade barriers increases risk to the UK economy. The Brexit squeeze has started and it will only get worse.
"The Prime Minister has chosen a painful path for the UK outside the EU, and this election needs to deliver a robust opposition in Parliament that will hold her to account and argue for alternatives."
