Question to the Department for Exiting the European Union :

To ask the Secretary of State for Exiting the European Union, if he will make an estimate of the potential average cost for a typical family of their weekly shopping in the event of the UK leaving the EU without securing any preferential trade agreements and reverting to standard World Trade Organisation tariffs.

My Department, working with officials across government, continues to undertake a wide range of data analyses to inform the UK's position for the upcoming negotiations with our EU partners. We have been clear that we will not provide a running commentary that might undermine our negotiating position.
