The leader of the Brexit Party called on Conservative party Members of Parliament to rebel against Boris Johnson's decision to allow Chinese tech giant Huawei to help build Britain's 5G network, which Mr Farage described as "the worst decision taken by a UK government for many years".
"Once Huawei is in the 5G network, getting it out will be all but impossible. For this reason, Johnson must reverse his decision to allow Huawei to take such a big position in creating 5G. A full-scale rebellion within Britain's ruling Conservative Party is the only way he can be guaranteed to change his mind," Farage wrote in Newsweek.
"I think the time has come for people to pick sides. The question is: are we to remain with the Western democracies that have always been our allies, or are we to throw our lot in with the Chinese Communist Party?" he asked.
