In today's ExchangeWire news digest: the CMA approves a merger between Warner Bros. Discovery and BT Group; Twitter reveals the financial cost of Musk's scrapped takeover; and a tech-licensing deal between the University of Manchester and a Chinese firm is blocked by the UK government.

Warner Bros. Discovery and BT Group merger approved in UK

The UK’s Competition and Markets Authority (CMA) has approved a USD$773m (£643.6m) agreement between media giants Warner Bros. Discovery and BT Group.

Under the deal, BT Sport will become a subsidiary of the American broadcasting company and be merged with Eurosport UK. The company, which is home to WWE and UFC in the UK, will also be able to earn USD$113.6m (£94.5m) over the next three years.

Twitter reveals it spent USD$33m on failed Musk buyout

Social media giant Twitter spent USD$33m (£27m) between April and June after Elon Musk offered to buy the company.

The platform, which reports 229 million users globally, also stated its daily users had increased 237 million during this time period, although it also reported a net loss of USD$270m (£224.8m).

The world’s richest man rescinded his offer to buy Twitter earlier this month and now faces legal action, in addition to a possible termination fee of USD$1bn (£832.6m).

UK blocks tech deal between University of Manchester and Chinese firm

An agreement that would allow the University of Manchester to license vision-sensing technology to a Chinese company has been blocked by the UK government.

The agreement between the university and Beijing Infinite Vision Technology Company Ltd, would have allowed the semiconductor company to develop, manufacture, and sell products using "Scamp-5"and "Scamp-7" vision sensors. The UK government, however, vetoed the deal under the National Security and Investment Act, citing concerns that the technology could be weaponised.
