On 22 July 2021, Dawn Butler, a Member of UK Parliament, was forced to leave the House of Commons by acting-speaker of the house for repeatedly calling Prime Minister Boris Johnson a liar. According to UK parliamentary rules Members of Parliament (MPs) are not allowed to accuse one another of lying in the House of Commons, and Butler outlined a number of occasions in which Johnson misled the public in recent months. Acting Deputy Speaker Judith Cummins asked Butler to reconsider her words, but Butler refused and repeated that Johnson had lied and was banned from parliament for the rest of the day. Is Boris Johnson a liar?
