The national public broadcasting company NPO is investigating why a party political broadcast by the PVV showing anti-Mohammed drawings was not transmitted as planned.

PVV leader Geert Wilders pledged to show the drawings during the broadcast but instead an old item was aired instead.

Wilders has accused the public broadcaster of sabotage and has now placed the item featuring the cartoons, which is 2.45 minutes long, on YouTube.

The video is due to be broadcast twice more later this month.
