The parent firm of Facebook and Instagram let the space at 1 Triton Square from British Land, the FTSE 250 commercial property company, in 2021 but never moved in.

Meta paid £149m to break the lease, which was understood by analysts at BNP Paribas to have 18 years left to run.

British Land said that despite the payment, the company's exit would reduce its earnings per share by 0.6% over the six months to next March.

But it said of the development in a trading statement: "Meta's surrender of our building at 1 Triton Square... enables us to accelerate our plans to reposition Regent's Place as London's premier Innovation and Life Sciences campus."

The decision leaves Meta with three other offices in the UK capital, including one owned by British Land.

British Land's trading statement was largely upbeat.

Chief executive Simon Carter told investors: "I am pleased with the continued momentum in the business.

"Operationally we are seeing strong leasing activity which reflects the exceptional quality of our portfolio and has resulted in our recent upgrade of the expected ERV (estimated rental value) growth in retail parks."
