Alex Zanardi says he has not agreed a deal to be part of Channel 4's comprehensive presenting line-up for its first season of Formula 1 coverage, despite being announced as such.

The former F1 driver, who continued racing successfully after losing his legs in a ChampCar accident in Germany in 2001, was named as part of Channel 4's vast presenting team alongside the likes of David Coulthard, Murray Walker, Susie Wolff and Mark Webber.

However, having not been included in any of the promotional imagery and with his role not defined at the unveiling, Zanardi - now a Paralympian gold medallist - has taken to Twitter to say he has never had a deal to be involved.

Channel 4, which won the F1 contract from BBC after it opted out of its deal early, will show ten race live in 2016, while - in an unprecedented move for a terrestrial commercial broadcaster - it will do so without advertisement breaks.

As well as his 2 gold medals at the London 2012 Paralympics, Zanardi returned to racing after his horrific accident at the Lausitzring with a race winning stint in the World Touring Car Championship driving a BMW with hand controls, and he has also competed in the Blancpain Sprint Series.
