Allsopp, 49, tweeted: “I see so many people on this forum who I know have taken illegal drugs, the transport & trade of which costs tens of thousands of lives, banging on about ‘Covidiots’. Where was your oh so strong moral compass when that blood soaked coke was going into your turned up nose?”
The TV presenter and mother-of-four went on to compare a breach of the lockdown Tier regulations to speeding or drinking too much.
