These fox cubs were caught on camera bouncing around on a family’s trampoline.

Martin Greenhalgh, 51, from Cardiff, had a security alert on his CCTV after the motion-sensor cameras picked up movement in his back garden.

He said he was stunned when he saw the four cubs jumping playfully.

“I looked at the camera and it was just amazing to see them there in the middle of the night,” he said.

Online tools which track user behaviour for advertisers have been found on a swathe of EU public health websites, including NHS and Gov.uk pages.

These trackers could compromise sensitive data about people, according to researchers at data protection compliance service Cookiebot.

The researchers also discovered trackers on 89% of EU government websites. Most of the trackers were developed by Google.

They were designed to “associate web activity with the identities of real people” Cookiebot said.

Of all the 28 EU member states, only Spanish, German and Dutch government websites were tracker-free.

“We of course expect everyone to fully comply with EU data protection rules and it is the responsibility of EU data protection authorities to ensure compliance,” a spokeswoman for the European Commission said.

But the public health website trackers presented additional risks, said Cookiebot.

“Over 100 advertising technology companies are systemically and invisibly tracking EU citizens when they visit their governments online, or when they access public health service resources about sensitive issues, such as pregnancy, sexual health, cancer or mental illness,” it explained.
