Boris Johnson has been urged to act after two more Conservative MPs were linked to figures spreading Covid conspiracy theories or making discredited claims.
Last week it emerged that Desmond Swayne, a former Tory minister, encouraged anti-lockdown street protesters to “persist” and suggested NHS capacity figures were being “manipulated” to exaggerate the impact of the virus.
Questions are now being asked about the judgment of a further two MPs: Andrew Bridgen – who defended Swayne in an interview on the YouTube channel of a controversial former BBC journalist whose posts have been taken down by YouTube for spreading false information about Covid – and Adam Afriyie, MP for Windsor.
