LONDON—British Prime Minister Theresa May fired her defense minister on May 1 over a leak of discussions in the National Security Council about Chinese telecoms company Huawei, the latest of her allies to be ousted from government.
The sudden dismissal of Gavin Williamson, who “strenuously” denied involvement in the leak, was another blow for May, who has been badly damaged by her failure so far to usher Britain smoothly out of the European Union.
