Britain's Secretary of State for Wales Alun Cairns is seen outside Downing Street in London, Britain, October 18, 2019.

British Prime Minister Boris Johnson’s minister for Wales Alun Cairns resigned on Wednesday, the first official day of the general election campaign, after being accused of lying about his knowledge of an aide who allegedly sabotaged a rape trial.

Cairns said last week he had been unaware that the aide had given evidence which led to the collapse of the case.
