Grouchy Rishi Sunak has refused to say whether he will order a probe into claims Suella Braverman tried to get civil servants help her avoid a speeding fine.
The PM also declined to say whether he had confidence in his Home Secretary in a tense exchange with journalists in Hiroshima, Japan.
He has been urged to order an investigation following claims Ms Braverman may have broken the ministerial code asking Home Office aides to arrange a one-to-one speeding course.
