Jacob Rees-Mogg says little evidence Brexit hit trade
The OBR said it was too early to know for sure because, for example, some of the barriers to trade agreed with the EU had not yet come into force.
It pointed to research from the Centre for European Reform, which concluded that in October 2021 the UK's trade in goods with the EU had been 15.7%, or £12.6bn lower, than it would have been without Brexit.
The gap had been between 11% and 16% each month of 2021.
