Has Dominic Cummings' car been 'egged'? Yellow stain seen on vehicle in Downing Street

Dominic Cummings' car may have been egged as he faces another day at the centre of a political scandal.

Yellow splatter stains were visible on the under-fire adviser's vehicle as he emerged from his north London home this morning.

A colleague was seen in the car, stained with what appeared like egg yolk smeared around the bonnet and front wheels this morning.

Boris Johnson is under pressure to sack Mr Cummings amid public outrage at his lockdown breach.

The PM is facing criticism himself after insisting his aide did nothing wrong on his trips between London and Durham during the nationwide lockdown.

A Met Police spokeswoman this morning said the force had not received any reports of criminal damage from the street Mr Cummings lives on.

The senior adviser also attracted heckles from his neighbours and passersby at his Islington address as news of his lockdown breaches emerged.

Neighbours were filmed leaning out of their windows to castigate the political adviser as he walked up the street yesterday toward his townhouse.

He headed into work today in the centre of a political storm, as the public, opposition and even some Tories call for him to stand down or be fired.

Mr Cummings travelled to Durham  in March to self-isolate with his family while official guidelines warned against long-distance journeys.

Number 10 said he left London because he feared he and his wife would be left unable to care for their son. 

Cabinet members closed ranks around Mr Cummings on the weekend before the PM backed him despite pressure to strip him of his role,  tweeting messages in Mr Cummings' defence over the weekend, saying he was trying to protect his family.

But a second joint investigation by the Mirror and Observer then revealed Mr Cummings took a second trip to the North East in April.

Mr Cummings was first spotted outside his parents’ property by a neighbour on April 5.

He was then reportedly seen walking by the River Tees near Barnard Castle on April 12 by retired teacher Robin Lees - 30 miles away from his parents' home.

Mr Cummings was reported to police last night for an alleged breach of lockdown.

Durham Police need to establish the facts surrounding whether Mr Cummings potentially broke any laws or regulations, the region's acting police and crime commissioner has said.

Acting Durham police, crime and victims commissioner Steve White said there was a "plethora" of additional information which deserved "appropriate examination".

He said he had written to the force's chief constable asking her to "establish the facts concerning any potential breach of the law or regulations in this matter".

Another police and crime commissioner said that Mr Cummings's actions have made a "mockery" of police enforcement of lockdown measures.

Gloucestershire's independent police and crime commissioner Martin Surl told BBC Radio 4's Today programme that Mr Cummings's actions will make it much harder to enforce lockdown restrictions.

He added: "I think it makes it much harder for the police going forward - this will be quoted back at them time and time again when they try to enforce the new rules.

"But I think more importantly it makes something of a mockery of the police action going back when the message was very, very clear: stay at home."
