Huawei gets UK 5G go-ahead

Ministers have reportedly approved the use of components built by the Chinese telecoms firm Huawei as part of the UK's 5G mobile infrastructure. It has been reported that the company will supply equipment for "non-core" elements of the new high-speed network. The move comes despite concerns from key intelligence allies, such as the US and Australia. Those countries, which form part of the Five Eyes alliance with the UK, Canada and New Zealand, fear the firm is too close to the Chinese government. Washington in particular has said it wants Huawei excluded from contracts. The company has insisted it is not controlled by the government in Beijing, but the chairman of the Commons Foreign Affairs committee has said allowing Huawei to build some of the UK's 5G infrastructure would "cause allies to doubt our ability to keep data secure". The BBC's security correspondent has written about whether Huawei is a threat to the Five Eyes alliance. And if you want to know more about 5G, click here.

Sri Lanka bomb suspect 'studied in UK'

Officials say one of the nine people suspected of carrying out the Easter Sunday bomb attacks against churches and hotels in Sri Lanka was educated in Britain. Sri Lanka's deputy defence minister told a press conference on Wednesday that the man had been in the UK before continuing his post-graduate studies in Australia. Authorities say they are looking into possible links between the locals who carried out the suicide bombings and the Islamic State group. The latest development comes after the death toll from the attacks rose again to 359 with more than 500 people wounded. The BBC has been examining what led to the carnage, who the victims were, and what we know about the attacks.

Trump and Twitter boss talk social media

US President Donald Trump has had a "great meeting" with Jack Dorsey, founder of social media giant Twitter, at the White House in Washington. The discussion was billed as being about "protecting the health of the public conversation" ahead of the US 2020 general election. Mr Dorsey tweeted afterwards that he wanted to make online discourse "healthier and more civil". And while the president - a prolific user of Twitter with around 60 million followers - also tweeted warm words about their chat, he had earlier used the platform to accuse it of being politically biased and of restricting the number of people who follow him. Twitter says follower numbers are reduced when it carries out periodic purges of so-called "bots". BBC News has looked into Mr Trump's Twitter activity - when he tweets, what he tweets, and who he tweets about.

How did the qwerty keyboard become so popular?

By Tim Harford, BBC World Service

It isn't easy to type "QWERTY" on a qwerty keyboard. My left-hand little finger holds the shift key, then the other fingers of my left hand clumsily crab sideways across the upper row. Q-W-E-R-T-Y. There's a lesson here: it matters where the keys sit on your keyboard. There are good arrangements and bad ones. Many people think that qwerty is a bad one - in fact, that it was deliberately designed to be slow and awkward. Could that be true? And why do economists, of all people, argue about this?

What the papers say

The Swedish teenage climate change campaigner Greta Thunberg features on several of Wednesday's front pages, after she met UK political leaders.
