The report cites an article published today in The Architects' Journal which details how Johnson secretly travelled to California in early 2013 to meet Apple executives and pitch the ambitious project, before he had received official backing for the scheme from his office.
Apple is well known for its intense interest in architectural design and its close attention to detail when planning and building its retail stores. However, it has little history of funding projects unrelated to its technology business, making Johnson's attempts to woo the company seem ill-judged.
In a statement given to The Architect's Journal, the London Mayor's office confirmed a meeting indeed took place with Apple to discuss "investment opportunities in London." However, Apple informed the publication that the company has "no involvement in this bridge project and is not considering getting involved."
