They are issues of great interest to Europeans, but cannot be fully understood through a single national lens. The climate crisis, geopolitics, people trafficking, economic insecurity – the biggest challenges are not limited by national borders. Which is why, this September, the Guardian is launching Guardian Europe – a dedicated English-language site with local, regional and global news for European readers.

To mark the launch of this new digital edition, the Guardian’s Europe correspondent, Jon Henley , will host a live and interactive online discussion with MEPs, leading political scientists and experts, to explore how the biggest challenges Europe faces today are reshaping the continent. Speakers include the Dutch MEP Sophie in 't Veld , the French writer and activist Rokhaya Diallo, and the political analyst and academic Catherine Fieschi . You will have the opportunity to put forward your own questions and comments during this livestreamed event.

Hopes fade of deal being struck, with one sticking point being right to occasionally breach detention centre standards

European Union member states have failed to reach an agreement on changes to the bloc’s migration laws after Germany and Italy clashed over key proposals relating to human rights guarantees in detention centres and the role of NGOs in facilitating migrant arrivals.

But, as hopes faded on Thursday of a deal being struck, ministers said they expected “fine tuning” in coming days to lead to a pact that would apply in the event of a sudden refugee crisis such as that of 2015 when more than 1 million people arrived from Syria and beyond.

Women aiming to reach UK or Ireland realised lorry was heading in wrong direction and contacted BBC journalist

Six women have been rescued from the back of a refrigerated lorry in France after a panicked text message to a BBC reporter set off a frantic cross-border search.

The women – four Vietnamese nationals and two from Iraq – spent more than 10 hours in the cramped space, surrounded by boxes of bananas, in hopes of making it to the UK or Ireland, according to the BBC .

Two MPs distance themselves from home secretary’s talk of ‘existential challenge’ as she called for human rights reform

Suella Braverman has been criticised by two Conservative MPs for an “alarmist” speech about the need for human rights reform due to the “existential challenge” posed by illegal migration.

Speaking from Washington DC on Wednesday, the home secretary riled some in her party by suggesting that being gay or a woman and fearful of discrimination should not be enough to qualify as a refugee in the UK.

European Council will update ministers from across bloc on controversial deal between the EU and Tunisia

Migrants from sub-Saharan Africa have spoken of their horror at being forcibly returned to remote desert regions where some have died of thirst as they attempt to cross the border into Tunisia .

After the European Union agreed to a €1bn (£870m) migration deal with Tunisia, human rights groups are urging Brussels to take a tougher line on allegations that Tunisian authorities have been pushing people back to deserted border areas, often with fatal results.

• ‘It’s a torment’: refugee tells how his family died in desert

Migrants from sub-Saharan Africa have spoken of their horror at being forcibly returned to remote desert regions where some have died of thirst as they attempt to cross the border into Tunisia.

As the European Union prepares to send money to Tunisia under a €1bn (£870m) migration deal , human rights groups are urging Brussels to take a tougher line on allegations that Tunisian authorities have been pushing people back to deserted border areas, often with fatal results.

Pato Crepin’s wife and six-year-old daughter were repeatedly pushed back by authorities in Tunisia, which has signed a €1bn deal with the EU

• ‘I had to drink my own urine’: Africans tell of being forced back into desert at Tunisia border

Pato Crepin had walked for three days through the desert and could not take it any more. Twice, he and his family tried to cross the border from Libya into Tunisia; twice, they had been pushed back. Crepin, who was recovering from an infection and had not had a drink for 24 hours, found he could not get up. In the blistering heat of the mid-July desert, his legs had given up.

His wife and six-year-old daughter, however, seemed stronger. Crepin, an asylum seeker from Cameroon, believed that if they left him behind they might yet make it to Tunisia and, from there, perhaps, on to Europe. He did not want to slow them down. “Go,” he told them. “I’ll catch up with you in Tunisia.”

Giorgia Meloni sets sights on foreigners who lie about their age to benefit from protection scheme for unaccompanied minors

• Europe live –latest updates

Foreigners who lie about their age to benefit from a protection scheme reserved for unaccompanied minors arriving in Italy will be deported under a security decree expected to be approved by Giorgia Meloni’s cabinet on Wednesday as part of her far-right government’s crackdown on irregular immigration.

The draft decree, parts of which were published by the Italian press, includes a measure stipulating that foreigners living legally in Italy will be deported if they are considered to be a threat to public order or national security.

Time to ditch the UN convention, said Braverman, we’d all been far too nice to people fleeing persecution

Call the US jaunt a win-win for Suella Braverman. Trying to get the rest of the world to ditch its obligations to the 1951 UN refugee convention was always a long shot, but there was the off chance that UK voters would be confused enough to imagine the home secretary was on top of the small boats chaos. More to the point, Braverman got to imitate a global player ahead of this weekend’s Conservative party conference.

No bad thing, when there might be a vacancy for a new leader within a year or so. There’s nothing the Tory right love more than someone who bounces around their own echo chamber. And here was Suella out-Kemiing Kemi. Imagining she was saying the things that cannot be said, when really all she was doing was cynically stoking a culture war. Not to mention blaming her own failures on international agreements. No matter. Braverman will say anything, do anything, to secure the Tory leadership. Though if Suella is the answer, the Tories should urgently ask themselves what exactly the question is.
