Dominic Cummings has said he should have resigned or admitted he had traveled to Barnard Castle during the lockdown.
The former chief adviser to the PM said he did not ignore the rules during his visit to Durham, but said he should have clarified.
He claimed that there were ‘security problems’ in his house, forcing him to move his family to his parents’ house.
But he admitted that the way No. 10 handled the result was “totally wrong” and admitted that he should have resigned.
His remarks came during an hour-long brutal attack on the Prime Minister, his wife Kerry and the government’s COVID response.
He sat down with the BBC’s Laura Kuensberg as he voiced his anger at his former office, which he left last year amid a power struggle.

Speaking about Barnard Castle he was shocked whether he had told the truth during a press conference in Downing Street’s Rose Garden.
Mr Cummings was the subject of ridicule last year, after claiming he had taken his family on a 30-mile trip to the palace in Durham to ‘test his eyesight’.
He said: ‘Everything I said in the Rose Garden was true but I didn’t go into all the safety concerns and background numbers.
‘There is no doubt that the way we handled the whole matter was wrong on Monday.
‘What I should have done is either just resigned and didn’t say anything about anything or I should have talked to my family and said listen we have to be clear about the whole thing.’
On claims of eye tests, he said: ‘The country was in a dire state, the prime minister almost died. It may sound strange but at the time it didn’t seem strange at all.
‘If you’re going to drive 300 miles to London tomorrow, go and drive up and down the road right now and see how you feel about the whole thing.
‘It was just about seeing if I was okay. If you can’t drive 30 miles you know you won’t be able to drive 300 miles the next day. It was as simple as that.
‘I understand people were upset but I didn’t ignore the rules, I had been discussing security issues with cabinet officials for months. It was appropriate to proceed regardless of the coronavirus situation.
In an interview with the BBC, he said as of mid-January 2020 – even before the arrival of Covid, the prime minister had ‘no plan to govern’
Elsewhere in the interview he admitted that he thought Boris Johnson being prime minister was ‘terrible for the country’, but he and ‘a few dozen’ supporters sought to use his premiership to their advantage.
The former de facto chief of staff at No 10 said he had found Mr Johnson to have ‘disappointing’ traits after working with him during the 2016 Brexit referendum, but agreed to assist him after entering Downing Street three years later. Happened.
But Mr Cummings, who left No 10 in the autumn after a power struggle, acknowledged he was now working to hasten the prime minister’s demise.
Asked during a BBC interview aired on Tuesday whether he wanted to ‘hurry’ Mr Johnson’s departure from Downing Street, he said: ‘Definitely. The sooner he goes, of course the better.’
In the hour-long broadcast, Mr Cummings said he had looked to ‘exploit’ the situation he found himself in the country after Mr Johnson came to power.
Mr Cummings asked if he had agreed to work with Mr Johnson to ‘make him do what you wanted’, answered: ‘To some extent, yes. He didn’t know what he was doing, but he knew he needed help.’
The Vote Leave mastermind said: ‘I think it’s terrible for the country but I keep trying to emphasize, you have to balance the different possibilities.
And he acknowledged that he and the rest of his Vote Leave colleagues had begun to clash with then-Carrie Symonds, who controlled the premiership.
‘From a practical point of view, all our choices were bad, so it was, which is the least worst option? The least bad option seemed to be to take advantage of the current situation and try to push things forward and put the country in a better position.
Asked who was behind the decision to support Mr Johnson on the grounds of getting Brexit, he replied: ‘Me and a network of people – some of us who did the Vote Leave campaign, some of us who did other things. Did it Maybe a few dozen.’
Mr Cummings also revealed he considered a coup against Mr Johnson only ‘days’ after the 2019 election – during which he helped secure one of the biggest general election victories in decades – to the Conservatives Johnson, fearing that the party leader’s then-girlfriend, Carey, was trying to sack vote leave workers.
He said, ‘Before mid-January we were meeting at number 10, it is clear that Carey (Johnson) wants to get rid of all of us.’
‘At that time we were already saying by the summer that either we would all be gone or we would be trying to get rid of them and get someone else as prime minister.’
He said there was a ‘big argument’ after Mrs Johnson, the former Tory communications chief, hired people and sacked them in ways that I thought were unethical and unprofessional.
The 49-year-old accused Mr Johnson of not having plans for office and said he “doesn’t know how to be prime minister”, claiming his “only agenda” is “buy more trains, buy more buses, more”. Build the world’s stupidest tunnel and bike – bus’ to Ireland.
