However, the EC’s leader expressed his belief that British people will make “reasonable” decisions, adding that all EU members expect the UK not to leave the EU. The EC’s warning was made in the context that the UK will hold a referendum on the issue on June 23^rd. Many Britons have not decided to support the UK’s leaving or staying in the EU.
