Expected to be called the iPhone 6s and 6s Plus, the handsets are expected to look identical to the current version - but include radically overhauled internals and a new force sensitive screen, along with a new 'rose gold' colour option.

A new Apple TV set top box is also expected to be unveiled, which can run apps.

Recent reports also claims the tech giant could be planning to release another handset just months later.

Apple suppliers are gearing up for the launch of a smaller 4-inch model dubbed iPhone 6C as soon as November - but according to 9to5Mac, it will not be revealed at the event.

'Don't expect a new 4-inch 'iPhone 6c' to show up on stage,' it said.

'Sources say that while Apple has been working on a new 4-inch iPhone with the capabilities of last year's iPhone 6, the device is not yet ready to ship.'

It also claims Apple has been prototyping an even smaller iPhone with a 3.5-inch display, the same size of the iPhone's screen from the first model in 2007 to the iPhone 4S in 2011 - but believes the product has been abandoned. 

It follows reports in May that a smaller, cheaper model would launch before the end of the year and feature the same Touch ID sensor seen on the flagship handsets. 

Apple typically launches its new handsets each year at an event in September and this year the firm is expected to release its iPhone 6S and 6S Plus. 

These models will be more powerful version of last year's 4.7-inch and 5.5-inch iPhone 6 and 6 Plus handsets. 

The much anticipated new version of its $69 TV box is also expected to be unveiled in September alongside new iPhones, and will run a version of Apple's iOS.

It is also expected to have a new, touchpad remote and boosted performance. 

'According to sources, this new Apple TV model, codenamed J34, will be the first model to run a full-blown iOS core,' 9to5Mac claims.

'Specifically, the new Apple TV operating system will be a TV-optimized version of iOS 9.,'It says the new device will be smaller and slimmer than the current version.

'We've heard that the new model looks like the prior Apple TV, but it is slimmer and slightly wider,' it said.

The new remote control will include touch-based input and gesture support, and the TV will use Apple's Siri assistant.

At last year's launch event, Apple had been expected to launch a iPhone 6C following the release of the 5C the previous year but these rumours were proved wrong. 

In May, images emerged online - which were believed to have been accidentally leaked by Apple itself - of a 4-inch phone that looked like the iPhone 5C but had a Touch ID sensor on its Home button. 

This Touch ID sensor launched on the iPhone 5S and is seen on the current flagship range.  

The reports about the November launch date appeared in China Times which claims supplier Hon Hai, which trades as Foxconn, has hired more employees to handle the production of a third device. 

It is not know how much the iPhone 6C will cost, but the 5C was marketed as a low-cost alternative to the flagship models and the 6C is expected to follow suit.

The 5C costs £319 ($450 in the US), for example, while the 5S costs £459 ($549 in the US) and the iPhone 6 starts at £539 ($649).
