Experts say young men and boys ‘with strong sense of grievance’ are ‘idolising’ shooters involved in US massacres. They are also falling through the gaps of UK terrorism laws

On the morning of 13 September, 18-year-old Nicholas Prosper was arrested while walking on a residential road in Luton. Minutes before, he had murdered his mother, younger brother and sister, shooting them dead in their family home.

Neighbours called police after hearing gunfire coming from the flat in Leabank tower, on Luton’s Marsh Farm estate, and officers found Prosper shortly afterwards on Bramingham Road. Later that day, searches of the area uncovered a loaded shotgun and more than 30 cartridges hidden in a nearby bush.

Director says Seven Jewish Children by Caryl Churchill, which provoked fury at its first production in 2009, is a ‘family story’ at heart

The premiere of Caryl Churchill’s short play Seven Jewish Children at the Royal Court theatre 16 years ago proved to be one of British theatre’s most controversial opening nights.

Total shows scale of dishonesty in undercover operations over more than three decades

• How women found truth about men who tricked them
• The spy cops who deceived women into sexual relations

At least 25 undercover police officers who infiltrated political groups formed sexual relationships with members of the public without disclosing their true identity to them, the Guardian can disclose.

The total shows how women were deceived on a systemic basis over more than three decades. It equates to nearly a fifth of all the police spies who were sent to infiltrate political movements.

The city’s madcap mix of bingo, dressing up and dancing has become a cultural phenomenon, bucking the trend of a declining UK club scene and packing venues nationwide. Ahead of the night’s 10th anniversary, our writer gives it a go

With her arms in the air, she is bellowing out the words and, indeed, the synth riff. It is 8pm. The woman is me.

Around me, everyone is doing exactly the same. To my right, a woman in full chicken costume is flapping her wings. To the left, a beautiful dark-haired girl, with the look of an Italian Dolce & Gabbana model at her rich husband’s funeral, is up with her crew, screeching, waving a glass of something sticky and deadly. I look around. I can’t see anybody – not a single person in the room – who isn’t singing along and dancing on the benches.

Exclusive: Leonie Mellinger believes media storm minimised her role as key part of Labour leader’s team

The media storm around Keir Starmer’s lockdown “voice coaching” was “revolting”, inaccurate and misogynistic, the woman at the heart of the row has told the Guardian.

Leonie Mellinger said parts of the British press had dismissed and minimised her role as a key part of Starmer’s team and used it as a “political weapon”. She added that it was “absolutely wrong” to describe her as a voice coach, and explained that she had worked on Starmer’s emotional connection when speaking in public, not on his voice or elocution.
