Sacha Baron Cohen’s new series Who is America? set to launch

Sacha Baron Cohen is to return to TV with a new satirical comedy series that will begin next week on Channel 4 in the UK and Showtime in the US .

The Borat star has been secretly filming the seven episodes for a year.

The show, which premieres on Showtime on Sunday, marks his first full series for TV since Da Ali G Show in 2004.

Showtime said Who is America? “will explore the diverse individuals… across the political and cultural spectrum” in the US.

The network promises it will show the comedian and actor “as you’ve never seen him before”. The series will begin in the UK on Channel 4 at 22:00 BST on Monday.

Last week, the comedian teased his comeback in a video showing Donald Trump berating him as a “third-rate character”.

Another preview clip shows former US vice president Dick Cheney apparently agreeing to autograph a “waterboard kit” – in reality a plastic water jug.
