Apple’s new flagship iPhone X features facial recognition technology and an "edge-to-edge" 5.8-inch screen while it also launched the iPhone 8 range.

In an event in Cupertino, California, CEO Tim Cook revealed the company’s upcoming smartphones.

The headline act was the X – referred to as ‘ten’ – which does not have a physical home button or fingerprint system ‘TouchID’. Users unlock the phone by looking at it: the ‘FaceID’ system recognises its owner using 30,000 infra-red dots, so it works in the dark.

The firm claimed there was a one-in-one-million chance that FaceID could be unlocked by a random stranger, compared with one-in-50,000 with TouchID.

Apple said its battery lasts two hours longer than the iPhone 7.

The iPhone X – which will be available in space gray and silver colours – is Apple’s most expensive phone yet. A 64GB capacity model will cost $999 (£999 in the UK) when it goes on sale on 3rd November. The 256GB version will be $1,149 (£1,149 in the UK).

Its previous most costly smartphone was the iPhone 7 Plus, which cost $969 (£919 in the UK).

By comparison, the new flagship Samsung Note 8 (64GB) comes in at $930 (£869 in the UK).

The firm also unveiled the iPhone 8 and iPhone 8 Plus, which retain the 4.7-inch and 5.5-inch screen sizes of its iPhone 7 predecessor.

Available in silver, space gray and gold, the 8 models - like the X - have glass on both the front and back, which enables wireless charging.

It has a higher resolution screen and improved camera for taking pictures and shooting video.
