British Prime Minister Theresa May fired her defense secretary Gavin Williamson on Wednesday. The decision follows Williamson’s suspected leak from a recent national security council meeting on China.

Specifically, he stands accused of leaking the council’s decision to allow the Chinese telecommunications business, Huawei, to provide some of the less-sensitive elements of Britain’s 5G telecommunications network. Williamson, an ardent pro-American, opposed that council decision and evidently hoped that he could see it overturned by publicizing it.
