Tuesday morning news briefing: PM's day of humiliation in Luxembourg

EU ambush: Luxembourg's PM accused of 'disrespecting' UK

Boris Johnson's attempt to kickstart Brexit talks has fallen into chaos after he walked into an ambush. Xavier Bettel, the prime minister of Luxembourg, "disrespected" Britain after he tried to force Mr Johnson to hold a press conference in a street full of anti-Brexit protesters. It left the PM no choice but to pull out - and then be sarcastically belittled with an empty lectern. Brussels Correspondent James Crisp has a reconstruction of how Mr Johnson took his begging bowl to the EU - and Luxembourg laughed in his face. Then, Mr Johnson was mocked by Guy Verhofstadt, one of Brussels' most senior figures. Read Michael Deacon's sketch of what happened. And see Matt's cartoon of the podium diplomatic incident from a different angle. As the legal battle over Mr Johnson's suspension of Parliament reaches the Supreme Court today, Asa Bennett explains everything you need to know about prorogation.

Meanwhile, Jo Swinson will today state she wants to be PM in her first speech to the Lib Dem conference as leader. She has already suffered a "David Steel moment" after she said her party was aiming for a majority in government - despite only having 18 MPs. Could they achieve a gargantuan swing to hit their 200 seats? Danielle Sheridan and Patrick Scott crunch the numbers.

E-cigarette dangers: Menthol vapes are linked to cancer

Menthol and peppermint vapes marketed at teenagers contain potentially cancerous levels of artificial flavouring, research has found. The study of e-cigarettes revealed high concentrations of a carcinogenic additive, which US watchdogs recently banned in food. As Health Correspondent Henry Bodkin reports, even moderate use of the increasingly popular products - available in shops across the UK - puts users significantly outside the "safe" threshold.

Booker Prize: 'Winner' named in error weeks early

It is one of the most coveted awards in the world of literature. And, a month before this year's Booker Prize ceremony, organisers have been forced to deny that the result has already been decided. As Anita Singh explains, copies of one novel have already accidentally gone on sale bearing "winner" stickers.
