Following the referendum, in which Broxtowe had a 54.6% vote to leave, Soubry criticised former Mayor of London Boris Johnson, who led the "Leave" campaign, accusing him of backing Britain's exit from the EU because he wanted to be Prime Minister: "My anger with Boris is that I don't honestly believe that he believed what he was saying to people". Appearing as a guest on BBC One's "Question Time" in June 2016, Soubry warned that some people who voted to leave the EU had disregarded tolerance, and describing it as " our country's finest hour". She urged the UK to put "hope over hatred" following the result.
