Amber Rudd has come under fire after referring to Diane Abbott as a "coloured woman" during a radio interview.
The work and pensions secretary made the comment during an interview with Jeremy Vine about online abuse suffered by women.
In response to a question about internet trolling, Ms Rudd said: "It definitely is worse if you're a woman, and it's worst of all if you're a coloured woman.

"I know that Diane Abbott gets a huge amount of abuse and I think that's something we need to continue to call out."
The Conservative politician has since apologised for her choice of phrase, writing on Twitter that she was "mortified".
"Mortified at my clumsy language and sorry to @HackneyAbbott," she wrote.
"My point stands: that no-one should suffer abuse because of their race or gender."
'Outdated' and 'offensive'
Responding to the comments, Labour MP Ms Abbott said the term "coloured" was "outdated" and "offensive".
"The term 'coloured', is an outdated, offensive and revealing choice of words," she wrote on Twitter.
The incident is the second slip up by a politician in a matter of weeks, with Angela Smith who defected to the Independent Group, saying people from black, Asian and minority ethnic backgrounds had a "funny tinge".
