Communications and Multimedia Minister Salleh Said Keruak has accused whistleblower site Sarawak Report of stalking and harassing Rosmah Mansor - the wife of Prime Minister Najib Abdul Razak.

In a blog post last night Salleh claimed the website had demonstrated "an absolute lack of decorum and manners", while harassing Rosmah - who is currently in London.

In a video of the incident it shows three individuals standing outside a compound of a house in what appears to be London.

One of the individuals, a man, is heard telling the person recording the video that they should not have come to London if they did not want to be photographed.

It is not known who these individuals are.
