A UK Government minister has resigned over the Dominic Cummings row.

Douglas Moray, parliamentary under-secretary of state for Scotland, has resigned over Mr Cummings' alleged breach of lockdown rules.

Prime Minister Boris Johnson's adviser Mr Cummings has faced a fierce backlash after it emerged he and his wife and child drove 260 miles from their home in London to stay in an "isolated cottage" in the north east of England - despite the government's advice to "stay at home".

On Tuesday morning, Mr Moray tweeted a picture of his resignation letter.

He said: "I haven't commented publicly on the situation with Dominic Cummings as I have waited to hear the full details. I welcome the statement to clarify matters, but there remains aspects of the explanation which I have trouble with.

"As a result I have resigned as a government minister."

Despite defending his actions at a press conference on Monday, the opposition and even some Conservative MPs are still calling for Mr Cummings to be sacked.

Speaking at a press conference in the garden of 10 Downing Street on Monday afternoon, Mr Cummings said his decision was based not only on fears over a lack of childcare if he became incapacitated with Covid-19 but also concerns about his family's safety.

He also defended his decision to drive to tourist hotspot Barnard Castle before driving home to London - saying he was just testing his eyes before embarking on a long journey.

In reply to questions from reporters, Mr Cummings said he had "no regrets" over the trip and had no intention of resigning.

Hours later, Mr Johnson faced questions about his aide's remarks during the UK Government's daily briefing.

When asked if he was prepared to revisit his decision to support Mr Cummings, he said: "I cannot give unconditional backing to anybody, but I do not believe anybody in Number 10 has done anything to undermine our messaging."

Mr Johnson also said he believed Mr Cummings had "spoke at great length" and said that he come across "as somebody who was doing the best for his family".
