Good Morning Britain was halted for a tragic breaking news alert as Marverine Cole shared details of a shooting in Australia. Marverine was in the ITV studio to deliver the rest of the day's news, alongside main presenters Richard Madeley and Charlotte Hawkins. "I'm bringing you some breaking news now. Two police officers are reported to have been killed in a shooting in Australia, according to broadcasters there," Marverine said.

She added that the shooter is still on the run in Victoria. Marverine issued an update later in the programme, telling viewers: "Police in Australia are responding to an active shooter in Australia. Two officers have been killed and another injured. Dog squads, armoured vehicles and tactical teams have been deployed. Schools and all public facilities have been locked down."

But furious GMB viewers said the same thing about the coverage - noting that the main programme hadn't yet mentioned the stabbing and arrests that happened at Notting Hill Carnival in London over the weekend.

One fumed: "Not reporting on the 400 arrests and multiple stabbing at a festival in London but reporting on a shooting on the other side of the world? Strange that."

A second echoed: "Wonder why Marverine isn't reporting arrests at London carnival? @gmb only tell us news they want us to hear like water shortage in Scotland. How many people there watch #gmb?"

A third posted: "What happened at notting Hill Carnival 2025 over the weekend? I'm not interested to hear from an idiot that's done more damage to this country than anyone."

Another added: "Nothing about over 400 arrest at London carnival @gmb? #gmb."

423 people were arrested at Notting Carnival over the weekend, including 46 for carrying and offensive weapon. Two people were also stabbed, but police confirmed the stabbings, which occurred at Powis Terrace and in Oxford Gardens, did not result in life-threatening injuries.

More arrests were made on Monday, with a total of 223 by 7.45pm. 177 were made at Carnival itself and 46 on the approaches to the event. It included 32 arrests for assaults on police, 46 for possession of an offensive weapon, 18 for sexual offences, and 146 in relation to drugs. There were also five arrests in relation to robbery, four for violence with injury, and 36 for 'other' violence.

The Metropolitan Police said that it has seen "far fewer incidents of serious violence than in recent years", but acknowledged the event is still in its latter stages and it is "not being at all complacent".
