Coronavirus: JK Rowling offers 'year's salary' to whoever wrote UK Civil Service's anti-government tweet

JK Rowling has praised an anonymous person who criticised Britain's government in a post on the UK Civil Service Twitter account - and she wants to reward them with cash. 

The since-deleted tweet in question targeted UK Prime Minister Boris Johnson and his senior advisor Dominic Cummings, calling them "arrogant and offensive". 

"Can you imagine having to work with these truth twisters?" the tweet continued, referring to the controversy over Cummings' alleged violation of lockdown rules during the coronavirus pandemic. 

After the tweet was deleted, the UK Cabinet Office Twitter account announced the tweet had not been officially approved, and the situation was being looked into. 

"An unauthorised tweet was posted on a government channel this evening. The post has been removed and we are investigating the matter," the tweet read. 

In response, Harry Potter author JK Rowling wrote: "When you find out who it was, let us know. I want to give them a year's salary."

Rowling also shared a screenshot of the tweet with a line of clapping emojis. 

Cummings prompted outrage when it was revealed he travelled 400km to see his parents despite government advice to stay at home. 

Cummings and his wife both had COVID-19 at the time and Government advice was to stay home if you had the virus. 

Despite widespread calls for Cummings resignation, Johnson insisted he would not fire his aide, who he said acted "responsibly, legally and with integrity" while arranging childcare for his son after his wife was diagnosed with COVID-19. 

Rowling called Johnson's position on the matter "despicable", in a furious Twitter tirade in which she likened the Prime Minister's response to giving the middle finger. 

"Parents all over this country have abided by the lockdown rules, even while ill themselves. Hundreds of thousands managed toddlers while shut up inside cramped accommodation, purely for the common good AS THE GOVERNMENT TOLD THEM TO DO," she wrote. 

"I can’t remember a clearer demonstration of contempt for the people from a sitting Prime Minister."
