Biggest cunt I've seen so far in the UK is the notoriously cuntish Mike Ashley, who owns Sports Direct (budget sportswear store), Jack Wills (clothing) and Newcastle United. First he tried to keep his stores open even after the government lockdown on non-essential business, by trying to make out that sportswear/clothing was an essential item for people needing exercise, and then it just came out that Newcastle are asking for money towards next season's season tickets.
Also the owner of Wetherspoon (budget large pub chain), Tim Martin, another notorious cunt, who until the last few days was telling people to keep going to pubs like his, then suggested he would not pay his employees the 20% of salary not paid for by the government, and that his staff should not hang around and go and get jobs at Tesco.
Both of them are due to be questioned by MPs.
