YouTube has been blasted after a study found extremist content remained on the site despite being flagged up.
YouTube and a host of other internet companies had pledged to weed out and remove such content in the wake of several high-profile terror attacks in the UK and across Europe.
Now a study by The Henry Jackson Society has discovered hundreds of video clips pertaining to neo-Nazism and the Taliban was still present on the video sharing service.
While the think tank's research uncovered a number of them had been removed, some videos flagged up for being offensive remained online.
Yvette Cooper, the MP for Normanton, Pontefract and Castleford who commissioned the report, condemned YouTube for this, saying it was "unacceptable."
She accused the company of taking too long to remove the content from their website, citing their promise and saying they "weren't moving fast enough."
