Reports of falling sperm counts and testosterone levels have fuelled fears over chemicals, pollution and modern lifestyles. But how much do scientists agree on what is affecting male fertility?

The world is unwittingly walking into a male reproductive crisis, scientists warned this week as they presented data that revealed an apparent halving of average male testosterone levels over the past 50 years.

“It is mind-blowing that testosterone has declined by 50%,” Prof Hagai Levine, who led the work, told the Guardian. “This is a lot. Wake up people. Wake up.”

Nigel Farage foresaw a summer stroll to glory when he forced a byelection – but now risks his career being trashed

The votes were being counted and the media had gathered for the moment that Andy Burnham, his sights on Downing Street, would be elected as the MP for Makerfield in greater Manchester. But Nick the Flying Brick, a candidate on numerous occasions for the Monster Raving Loony party, could not help but be distracted. How could it be that the candidate across the Edge Conference Centre with a silver bin on his head had managed to secure the 10 local nominations necessary to stand?

The Flying Brick, real name Nick Delves, 60, who is also treasurer for the Loony party, had knocked doors-a-plenty to get the nominations for his veteran candidate, Howling Laud Hope. Yet, the Flying Brick hadn’t seen any chaps on the streets with bins on their heads. Certainly not in recent days. Not a single one.

Three years ago, the pop star was riding high after a sellout tour. But then a slew of shocking accusations from her former dancers changed everything. Where does she go from here?

On 30 July 2023, Lizzo finished a 10-month world tour. She had played 80 shows across North America, Europe, Oceania and Asia, selling more than 853,000 tickets and grossing $86.3m. The rapper turned pop star was on top of the world. Then everything came crashing down.

Two days later, three of her former dancers alleged that they had been subject to sexual harassment, a hostile work environment, religious and racial discrimination and fat-shaming on the tour. Two had been sacked, and one resigned. After the accusations, there was a huge pile-on from mainstream media and social media. And it seems to have gone on ever since. Lizzo, whose real name is Melissa Viviane Jefferson, disappeared. We were told that she was busy recording the follow-up to her huge hit album Special. But there were also rumours that she’d had a terrible breakdown.

The people of Bryne are proud of local hero’s rise to the top of world football as Norway prepare to face England

Surrounded by red hats, No 9 shirts and Erling Haaland action toys at her fabric shop in the small Norwegian town of Bryne, Olinda Haaland – no relation but proud to share the now world-famous name – said everybody in the striker’s home town was a football fan these days.

“It’s been pure joy,” she said of her namesake’s rise to the top of world football. “We all love him so much and he’s doing so much for Bryne.”

Abigo, 26, a supervisor in retail, meets Suli, 25, an animation graduate

What were you hoping for?
To meet someone I felt comfortable around and easy to talk to.

We were in Corfu for a cheap and cheerful tennis trip and every day brought a new disaster. The swimming pool had no water. The tennis rackets had no strings. And don’t get me started on the family-run restaurant

My boyfriend and I took up tennis a couple of years ago. After 18 months of group lessons in our local park, many of them cancelled or abandoned due to rain, we started fantasising about playing somewhere sunny. Perhaps at a nice hotel with a pool, and yoga classes, and delicious food …

A quick search for tennis holidays put paid to that dream. They all seemed to be in luxury resorts and cost a fortune. Undeterred, I decided to plan a DIY tennis trip. I found a cheap aparthotel in Corfu. It looked no-frills but perfectly nice – spacious rooms, a pool, pretty gardens and, crucially, a tennis court. Best of all, it was cheap as chips in March.

Officers are carrying out ‘numerous inquiries’ but 26-year-old, arrested on Friday afternoon, is no longer part of the investigation

Ann Widdecombe had stepped down from Westminster in 2010 at the age of 62, after 23 years as an MP, seven of them as an uncompromising and often divisive junior minister under John Major.

But having been passed over for a peerage, she had no interest in a quiet retirement. Widdecombe may have been a devout Catholic with hardline views on morality and law and order, but she did not take herself overly seriously.

Thinktank urges prospective prime minister to reclaim UK’s role as an international leader on development

Influential backbenchers are calling on Andy Burnham to reclaim Labour’s leadership on international development and chart a course back to spending 0.7% of national income on overseas aid.

In a collection of essays to be published soon by the New Economics Foundation (NEF) thinktank, MPs lay out proposals for a Burnham-led government to rethink foreign policy.

Plans specify tolls must not be compulsory, as US officials urge Iran to make public statement that strait is open and that shipping can safely pass

Europe is studying proposals that may allow the charging of navigational fees in the strait of Hormuz so long as the tolls are not compulsory and have the support of the UN agency that regulates maritime transport.

Britain’s deputy prime minister, David Lammy, said the imposition of compulsory tolls would be disastrous. But some of his cabinet colleagues said they recognised that systems of payments for specific navigational services were permissible in many natural waterways, including the strait of Malacca and the Channel.

Teachers call for schools to be urgently adapted for hot weather amid reports of nausea, fainting and heatstroke

The extreme heat that has hit the UK twice in the past few weeks has left teachers struggling to cope as temperatures in some classrooms climb above 40C, with pupils and staff suffering from heatstroke, nausea and headaches.

Teachers say they have been desperately trying to keep children safe, with some covering younger pupils in wet paper towels as they lie on the floor, while older students have been given trays of water under their desks to put their feet in.
