#AbolishTheMonarchy began trending on Twitter after Queen Elizabeth II agreed on Wednesday to suspend Parliament.

She approved Prime Minister Boris Johnson's request to shut down Parliament from September 9 to October 14.

That will give MPs looking to prevent a no-deal Brexit just days to act before the UK leaves the European Union on October 31.

Though the request is considered typical under the UK Constitution, many British people still criticized the decision as undemocratic.

The actor Hugh Grant even chimed in, calling Johnson an "over-promoted rubber bath toy" in an angry tweet.

Queen Elizabeth II has been criticized for agreeing to shut down Parliament for almost a month.

At the request of the newly appointed prime minister, Boris Johnson, Parliament will be suspended from September 9 to October 14.

This means MPs looking to pass legislation to prevent a no-deal Brexit will have limited time to do so, as the UK is set to leave the European Union on October 31.

As the request is considered typical under the UK Constitution, the Queen "had to approve it," the Daily Express royal correspondent Richard Palmer said.

"The Queen has been dragged into a constitutional crisis. #AbolishTheMonarchy has been trending on Twitter," Palmer tweeted. "But although constitutional experts have described the PM's lengthy suspension of Parliament as an affront to democracy, they agree that the Queen had to approve it."

Nonetheless, the British public expressed anger at her decision, and #AbolishTheMonarchy ended up trending on Twitter, with 20,000 tweets on Wednesday.

"Unelected head of state shuts down parliament at the request of the unelected PM. Democracy!" one person wrote.

Another wrote: "To anyone looking to justify the Queen's actions today with the line, 'she had no choice, she was just following protocol and convention', that is precisely why we should #AbolishTheMonarchy. If she is unable to apply critical thought to her function then she is utterly pointless."

Meanwhile, a fan account dedicated to the Duke and Duchess of Sussex wrote that "the monarchy has obviously had its run."

"The Queen has obviously lost the plot," the account tweeted.

Thousands of people protested outside Parliament on Wednesday evening and Thursday morning, while a petition against the suspension of Parliament had gained more than 1 million signatures as of Thursday.

Even the British actor Hugh Grant made his opinion clear, calling Johnson an "over-promoted rubber bath toy" in a scathing tweet.
