A British teenager who killed three young girls at a Taylor Swift-themed dance event was jailed for at least 52 years on Thursday, for an attack Prime Minister Keir Starmer called one of the most harrowing moments in Britain's history.

I consider it likely he will never be released,” judge says, adding that Axel Rudakubana must serve a minimum of 52 years in detention for his “extreme violence”.

A British teenager on Monday pleaded guilty to charges of murdering three young girls in a knife attack in northern England in July, a crime that horrified the nation and was followed by days of nationwide rioting.

A British teenager unexpectedly pleaded guilty on Monday to murdering three young girls at a Taylor Swift-themed dance event last July, while the government said it would hold an inquiry into the atrocity which was followed by nationwide rioting.

Keir Starmer has said the Southport killings by teenager Axel Rudakubana 'must be a line in the sand for Britain' and there must be “fundamental change” in how the country protects its children. It comes as the government said they will undertake an inquiry into the 'barbaric' murders of three young girls at a Taylor Swift dance class last year.
