The bottom line

£87m The cost so far of building the new set for EastEnders, according to the BBC soap’s producers. The project is running four years late and £27m over budget; £44,000 alone was spent on sample bricks from Belgium and India. The original set was built in 1985.

£10bn How much it would cost to switch to driverless trains on the London Underground, according to a 2020 feasibility study. The government says it still wants to explore the option as part of an agreement for longterm funding for Transport for London.

$93bn The total expected cost of Nasa’s Artemis lunar programme by 2025, the space agency’s inspector-general has warned. Each mission, as part of the programme to return US astronauts to the moon, is expected to cost around $4.1bn.

£125,250 How much the gold Rolex watch owned by actor Michael Caine sold for at auction with Bonhams in London last week – ten times its upper pre-sale estimate. Furniture, artworks and jewellery stemming from his career also featured in the sale.

£624m How much the government has committed to tree planting and peat restoration as part of climate goals. However, landowners aren’t applying for funds, and a maximum 1,900 hectares are expected to be planted this year, against at least 2,577 that had been planned. £200 The price of a Stem Player, a musicplaying device that rapper Kanye West (pictured) has designed with British tech company Kano Computing. West is releasing his new album, Donda 2, exclusively through the device that allows listeners to break down the elements of a track into “stems”, such as the vocals and drums, as well as to add their own effects.
