A job advertisement for what could be the most glamorous admin role in the world on Virgin boss Richard Branson’s Necker Island has gone viral.

The listing for a "personal assistant and admin assistant", posted on social networking site LinkedIn, has received widespread attention after it offered one lucky applicant the chance to relocate to the billionaire’s private Caribbean island.

"Fancy working on Necker Island?" It begins, "Thought so!"

The advert says hopefuls can expect the job to be split across “two busy offices” and will be asked to deputise for Mr Branson’s PA when they are on holiday.

“It’s a busy role in two even busier offices so think carefully as it’s not for everyone, despite the sunshine,” the job description states.

“We are of course looking for someone with fantastic admin and organisational skills as well as practical experience in a busy office. But your personality is just as important.

“As well as being a top notch administrator, we’re also looking for someone who is self-motivated, outgoing and enthusiastic who can balance this with the essential need for discretion and confidentiality.”

Applicants are asked to submit their CV alongside a video no more than two minutes long, explaining why they should be given the job.

They were also asked to provide “an interesting fact” about themselves in their video pitch.

The closing date for applications is 10 March.

Virgin founder Mr Branson purchased 74-acre Necker Island in 1978 for just $180,000 and turned it into a private retreat.

Part of the British Virgin Islands, Necker can accommodate more than 30 guests at any one time, while a night’s stay costs somewhere in the region of £40,000.
