Dame Vivienne Westwood has been at the forefront of fashion ever since she started selling her punk-inspired designs in Sex Pistols manager Malcom McLaren's influential King's Road boutique, Sex, in the Seventies.
But now the eccentric designer, whose eponymous label is worn by the likes of Kate Moss, Angelina Jolie and Theresa May, fears for the future of her empire as she claims it is under attack from a powerful insider.
'I've got a problem with an evil person who's trying to break up the whole company. He's the devil,' she tells me, adding that such is the urgency of her predicament, it was one of the reasons she skipped celebrating her 78th birthday earlier this month.

A spokesperson for the firm was unavailable for comment about any break-up, which could potentially see parts of the company sold off.
The rumoured coup attempt comes at a particularly bad time as she is entangled in several ongoing and time-consuming battles.
These include 'saving the world' and her support for WikiLeaks founder and former fugitive Julian Assange, whom she visited regularly during his near seven-year sojourn at the Ecuadorian embassy in London before his arrest last week.
Vivienne's husband of 27 years, Andreas Kronthaler, took over the reins of her label earlier this year which allows her to focus more on her political campaigning and activism.

'I work under a lot of stress but it's exciting stress — most of the time. It just means you don't sleep and your head's forever in the world.
'I'm the best person at analysis and I have a strategy to save the world. I'm the only person who's analysed: this is the problem to start with, and this is the solution.'
Hurrah! Someone tell the Extinction Rebellion mob...
