Efforts to rid Huawei from Britain’s 5G mobile network were a constant feature of Tory politics last year. The question of whether a company with links to the Chinese state should be involved in such sensitive infrastructure dominated much of 2020, culminating in Oliver Dowden’s announcement in November of a ban on Huawei in 5G networks. It followed a long-running campaign by the 40 or so MPs who belong to the China Research Group, run by Tom Tugendhat, the chairman of the Foreign Affairs Select Committee.
