It was late January and Elon Musk had just announced a change of gear at Tesla, the world’s largest electric car company. In the teeth of a global supply chain crisis, the firm would not be releasing any new models until at least 2023. But America’s $230bn (£194bn) tech tycoon had found another focus for his attention. Within days, he had begun investing large sums in Twitter shares, to build a stake that eventually reached more than 9%.
On 26 March, Musk held a conversation with his old friend Jack Dorsey. But this wasn’t an informal catch-up: Dorsey, who co-founded Twitter, had retained a seat on its board and the two men, along with another board member, discussed whether Musk should also become a director.
