A key reason for the layoffs is Meta’s increased spending in other areas of the company, including AI, for which it will this year spend $135bn (£100bn). This is roughly equal to the amount it has spent on AI in the previous three years combined, according to a person who viewed the memo.

US President Donald Trump continued to strike a defiant tone as the US-Iran conflict continued amid the ongoing ceasefire.

Mr Trump said he has ordered the US Navy to “shoot and kill any boat, small boats though they may be… that is putting mines in the waters of the Strait of Hormuz.”

US Central Command said it has ordered 31 vessels to turn around or return to port since the blockade of the Strait of Hormuz began.

While the US Defence Department said on Thursday that its forces boarded a vessel in the Indian Ocean that was transporting oil from Iran.

More optimistically, various news outlets reported that an Iranian diplomatic source told the Russian news agency Ria Novosti on Thursday that preparations for negotiations between Iran and the US in Pakistan could lead to a breakthrough as early as tonight or tomorrow.

AJ Bell analyst Dan Coatsworth noted: “There continue to be mixed messages around peace talks, creating an air of uncertainty that periodically stops investors in their tracks.

“It’s one of those days where investors have dialled back risk appetite to consider what could go wrong, rather than shrugging off the backdrop of conflict to bid markets higher.”

Brent oil traded at 103.25 dollars a barrel on Thursday afternoon, compared to 101.42 dollars at the time of the equities close in London on Wednesday.

In the UK, the private sector regained growth momentum in April, according to preliminary purchasing managers’ index survey results released by S&P Global.

The flash PMI composite output index registered 52.0 points in April, above the 50-point mark that separates growth from contraction, and up from March’s reading of 50.3 points, indicating an accelerated pace of growth.

The reading came in ahead of FXStreet-cited market consensus, which had forecast the UK private sector would slip into contraction with a 49.8-point PMI reading.

JPMorgan analyst Allan Monks noted a surge in input price readings, including within the less energy-intensive services sector.

In addition, the jump in output price readings also indicates that pricing power is “alive and well”, he said.

While the labour market “remains weak”, it’s a “reoccurring theme in the UK data that growth, wage and pricing pressures continue to hold up despite the stall in hiring,” he said.

Mr Monks thinks the report suggests inflation risks should dominate growth risks in the Bank of England’s thinking when it considers interest rates.

Legal & General fell 5.6% as it traded ex-dividend, as did Fresnillo, which fell 6.4%.

Sainsbury, down 3.7%, was another in the red as the food retailer warned that the Middle East crisis could squeeze profit in the current financial year.

“The conflict in the Middle East will impact both our customers and our business,” it said in a statement as it reported full-year results.

“The duration and extent of these impacts is very uncertain and this is reflected in our profit guidance.”

Chief executive Simon Roberts pledged to do “everything we can” to support customers over the coming months, with “absolute focus on keeping prices low”.
