Environment Secretary Michael Gove described the Labour Party’s Brexit plans as “bollocks” during House of Commons debate.
Referencing reports that Shadow International Trade Secretary Barry Gardiner had referred to Labour's official Brexit position in the same way, Mr Gove said he agreed.
Praising the Brent North MP's "truth and perfect clarity", Mr Gove said the Commons was grateful for his casting of light on "the testicular nature" of Labour's six Brexit tests.
Mr Gove said: "He summed them up, pithily, in a word which in Spanish translates as 'cojones' and in English rhymes with 'rollocks'.
"I know, Mr Speaker, there are some distinguished citizens in this country who have put on their cars a poster or sticker saying 'bollocks to Brexit' - but we now know from Labour's own frontbench that their official Brexit position is bollocks."
Mr Gove added: "I have to say that the shadow international trade secretary is a jewel and an ornament to the Labour front bench.
"He speaks the truth with perfect clarity, and in his description of Labour's own policy can I say across the House we're grateful to him, grateful to the constant Gardiner for the way in which he has cast light on the testicular nature of Labour's position."
His remarks came as he opened the latest day of debate on Theresa May's Brexit deal.
Liberal Democrat former minister Sir Edward Davey called a point of order, asking whether Speaker John Bercow had "made a new ruling on Parliamentary language which I am not aware of?"
Mr Bercow responded that Mr Gove had not been disorderly and use of the word was "a matter of taste".
He said: "I have made no new ruling on Parliamentary language and I was listening, as colleagues would expect, with my customary rapt attention to the observations of the Secretary of State for Environment Food and Rural Affairs.
"I richly enjoyed those observations and particularly his exceptionally eloquent delivery of them, which I feel sure he must have been practising in front of the mirror for some significant hours.
"There's nothing disorderly - because a number of people were chuntering from a sedentary position that the use of the word beginning with B and ending in S, which the Secretary of State delighted in regaling the House with - was it orderly?
"Yes, there was nothing disorderly about the use of the word - I think it is a matter of taste."
