Adrian Chiles investigates the extraordinary rise of electric bikes on our streets and what that means for drivers, pedestrians and cyclists. He asks whether, despite their green credentials, they are a solution to our congested towns and cities or a new menace in need of tighter regulation. He discovers that some more powerful and faster e-bikes, while openly sold as commuter bikes, are illegal to ride on the road. Sales of e-bikes have boomed but, as they are crammed into the same space as pedestrians and other road users, councils and the police are struggling to cope with the e-bike revolution.

Zoe Conway talks to those on both sides of the divide, investigates how the world of work is changing, and asks what it means for our towns and cities.

Huge clean energy projects are stirring anger across Britain. The government says new pylons, solar plants, wind turbines and electricity substations are essential to meet its bold plan to decarbonise the country’s electricity by 2030. It says it will 'streamline' the planning process to get these projects through quickly and help get the economy growing.

For Panorama, Justin Rowlatt meets protestors, energy secretary Ed Miliband and Oscar-nominated actor Ralph Fiennes, who are all taking sides in the battle over rewiring Britain.

Five years ago, schools across the UK were given just a few days’ notice as the country locked down in response to the pandemic. For most children, it was the start of nearly two years of interrupted schooling and lost learning. For many of the youngest, it often meant missing out on activities which are vital for early development. Babies born in lockdown are now in their first year at primary school.

For some children, there has been a significant impact on their speech, language and other communication skills, and on their social development. Branwen Jeffreys spends time with families and teachers to discover how they are meeting the challenge of bridging the gaps and helping their children to catch up.

Reporter Darragh MacIntyre meets the victims who have been publicly vilified. They don’t know why they were targeted, and they haven’t been able to get the messages taken down.
