Following the acquisition of Air India by the conglomerate, Tata Group, the airline will spend more than $400 million to refurbish the interiors of its entire wide-body fleet.

The company on Thursday said the overhauling and upgrade to part of plans to attract more flyers.

“Air India has committed to attaining the highest standards of product and service befitting of a world-class airline. We know that, at present, the cabin product on our 40 legacy widebody aircraft falls short of this standard,”

The refurbishment will involve the introduction of a premium economy cabin, it said in a statement, adding that the first aircraft with refurbished interiors will enter service in mid-2024.

In November, Tata Sons and Singapore Airlines (SIA) revealed that they will merge Air India and Vistara to create India’s second-biggest carrier in a deal where SIA will hold a 25.1% stake in the entity with an equity infusion of Rs 2,058.50 crore. Tata will hold the rest.

The Tata Group paid nearly $2.4bn (£1.7bn) to take over debt-ridden India’s national carrier, Air India in January 2022.

Germany on Wednesday foiled a violent overthrow of the state to install as national leader a prince who had sought backing from Russia.

German authorities have detained 25 members and supporters of a far-right group.

The attempted coup was according to the prosecutor influenced by the deep state conspiracy theories of Germany’s Reichsbuerger and QAnon, whose advocates were among those arrested after the storming of the US Capitol in January 2021.

An Interior Ministry spokesperson said security agencies were looking closely at any possible contact with Russia.

The Kremlin said there could be no question of any Russian involvement in an alleged far-right plot to overthrow the German state, with spokesman Dmitry Peskov saying that it “appears to be a German internal problem”.

The group had emulated the structure of the government, creating a “council” that had regularly met since November 2021 as an administration-in-waiting with different departments, such as foreign affairs and health, prosecutors said.
