A Labour student group is in hot water after joking about killing Queen Elizabeth II.

On Tuesday, the UoL Labour Students shared a sketch of an execution. "It's 369 years the execution of Charles I. Happy #RegicideDay, comrades! We did it once, we can do it once again," the caption read.

Regicide is the act of killing a king. Since Queen Elizabeth II is the reigning monarch, the post implies that it was targeting Her Majesty. This did not sit well with majority of people who come across the post.

"Dear @MerseyPolice I, and many others, take offence at this open and public desire to kill our reigning monarch, Queen Elizabeth II, by the Labour Students of University of Liverpool. We kindly request that the responsible people are brought to swift justice. #HateSpeech," one Twitter user wrote in the comments.

"Its no good - you called for the murder pf the queen - better to have left it up so we could see what you really believe in - socialism always ends in the killing of the people - will you never learn?" another user added.

"You do know that calling for the death of the monarch is treason, in other words, lots of jail time," Dee Bee said.

A number of Twitter users took action by reporting the post to the police. Some even tagged the Merseyside Police's account. The department has already responded to the controversial post.

"We have received numerous reports of comments made by a Twitter account regarding regicide. Thank you for your messages, the matter is currently being looked into further," Merseyside Police wrote.

Meanwhile, the labor group has already deleted the post and has since apologized for the offensive tweet. According to them, it was meant to be "tongue in cheek" comment and that they do not advocate regicide. But their critics were not convinced.

"You are worried about the consequences rather than being sorry for the original post. There was nothing to indicate it was a tongue in cheek comment & you deserve the full force of the law for advocating regicide," Richard Northey wrote.

"There are consequences to your actions that a mere apology will not stop," another user wrote.
