Stanley Johnson, father of Boris Johnson, has come under criticism for making allegedly Islamophobic comments during a live election night show on the UK's Channel 4.
He said: "If I was a female fighter jet pilot, I would expect someone to say 'don't wear a burqa.'"
A fellow panelist on the show labelled the comment as "disgraceful".
Boris Johnson has been accused of Islamophobia in the past, having previously said in a newspaper column that women in burqas "look like letter boxes".
Niqabs and burqas were at the center of a controversy involving Boris Johnson last year, when he likened Muslim women who wear veils to "letter boxes" and "bank robbers" in his column for the Daily Telegraph newspaper.
He has since partially apologized, saying at the launch of his bid to become Prime Minister this summer: "In so far as my words have given offense over the last twenty or thirty years when I've been a journalist and people have taken those words out of my articles and escalated them. Of course, I am sorry for the offense they have caused."
On the same show tonight, the Canadian comedian Katherine Ryan confronted Boris Johnson's father on the issue of single motherhood.
That came shortly after his son was criticized for a 1995 newspaper column in which he called the children of single mothers "ill-raised, ignorant, aggressive and illegitimate".
