A black MP has claimed she was “mistaken for a cleaner” in Westminster by another MP.

Dawn Butler, Labour MP for Brent Central, said she stepped into a members-only lift when a House of Commons member – who she has not named – told her that the “lift really isn’t for cleaners”.

The 46-year-old said that this incident of racism has been one of “so many incidents” she has had to endure in Parliament since becoming an MP in 2005.

Other incidents that Ms Butler, who is the daughter of Jamaican immigrants, has described include an occurrence when she was asked whether she was allowed in the members area of the Palace of Westminster terrace by a former minister in 2008. Ms Butler said that when she told the minister that she was an MP, he replied with: “They’re letting anybody in nowadays.”

Following Ms Butler’s appearance on BBC 5 Radio Live, where she discussed the racism she received, former London mayor Ken Livingstone stated that the situation was “ridiculous” as she frequently “gets up and speaks” in the Commons.
