Labour would part-nationalise BT in a bid to bring free high-speed broadband to all homes and businesses in the UK by 2030, shadow chancellor John McDonnell has promised. As well as taking Openreach - the bit of BT which runs the broadband network - into public ownership, Mr McDonnell said the £20bn scheme, called British Broadband, would eliminate bills for millions of people. The cost of maintaining the infrastructure would be paid for by a tax on tech firms.  The Conservatives - who have pledged £5bn to bring fibre broadband to every home by 2025 - dismissed Labour's plans as "fantasy", while the Liberal Democrats said nationalising Openreach was a "waste" of taxpayers' money. While BT itself has said it's happy to work with whoever wins the election to deliver "a digital Britain", the umbrella organisation for the UK's technology industry said the plan would be a "disaster" for firms.  If you want to know more about full-fibre broadband, click here.

Elsewhere in the general election campaign on Friday, the Conservatives have said they will cut business rates to help boost "left-behind towns", while the Lib Dems are pledging £100bn to tackle climate change and protect the environment.  The Scottish National Party, meanwhile, is calling on the UK government to "hand back" £175m paid in VAT by Scotland's police and fire service. The SNP is accusing ministers of refusing to refund the money, despite accepting it should not have been paid. For more election coverage throughout the day - including rolling text commentary and updates - visit our Election 2019 page.

The number of children being treated in NHS hospitals for anaphylactic shock has risen every year for the past five years, figures show. According to the NHS, 1,746 children were treated in 2018-19, up from 1,015 in 2013-14. It's thought environmental factors, such as dietary changes, exposure to microbes and pollution, may play a role in the rise. The mother of Natasha Ednan-Laperouse, who died in 2016 after eating a takeaway baguette containing sesame , said the figures show there is an "allergy emergency".

A BBC investigation has discovered that nitrous oxide - the second most commonly used recreational drug in England and Wales - is being sold with the equipment needed to take it as a high on sites like Amazon and eBay. BBC Wales found some sellers were happy to sell and deliver round the clock. The problem for the authorities is that nitrous oxide - also known as "nos" - has legitimate applications in catering and pain relief - but trading standards say online sellers need to "take responsibility" to prevent illicit use . Amazon says it has since removed products being sold as a package of nos canisters and balloons, while eBay said "listings encouraging illegal activity are banned from eBay's platform".
