Fans have been given their first look at what could be the last ever episode of Ant and Dec’s Saturday Night Takeaway which the pair have said will be "the party to end all parties".

The 20th series of Saturday Night Takeaway is set to conclude with a two-hour live grand finale special on Saturday, April 13 which will feature the likes of Simon Cowell, Girls Aloud, Kaiser Chiefs and Holly Willoughby.

Ant and Dec have previously revealed this would be the last series of Saturday Night Takeaway "for a little while" stating they were giving the show a "rest" so they could take some time away from the ITV show.

The Geordie duo launched the ITV entertainment show back in 2002 and it has now run for 20 years.

It has featured on ITV ever since, apart from a short hiatus from 2009 to 2013 while the presenters pursued other projects.
