Saudi Aramco CEO: Diversifying is 'timely and overdue'

As part of the Saudi royal family's recently announced Vision 2030 plan to modernise the Kingdom, it will sell shares in the state oil company Saudi Aramco on international markets.

It would be the most valuable company in the world, by some estimates worth over $2trn (£1.4trn) - four times the size of its next rival, Apple.

As part of the process, the normally secretive company invited a select group of journalists for a rare visit to its HQ in Dhahran, eastern Saudi Arabia, to meet senior chief executives and hear the company's plan to play a key role in Saudi Arabia's modernisation efforts.

The BBC's Simon Jack spoke to the company's chief executive, Amin Nasser.
