The UK government must push back against China immediately. Beijing's consistent attempts to influence the direction of the UK from the shadows while committing a series of human rights violations domestically can't be tolerated. London's relationship with Beijing must be drastically reimagined with immediate effect.
The UK's baseless allegations against China are without evidence and merely an attempt to politicize the issue of cybersecurity at the behest of Washington. The UK's smear campaign is both illegal and ineffective, and all sanctions will merely provoke a legitimate, tough response from Beijing.
Despite the threat, the UK has been slow with its meek reaction to Beijing's attacks. The government seems both scared and tentative to do any more than apply weak sanctions to minor individuals connected to Beijing. The government's current response to attempts to undermine British democracy has so far been desperately lacking in teeth.
