Mumbai: July 23, 2008 - Amitabh Bachchan is on a world tour with family but he is not happy. Big B has written in his blog that certain forces are out to sabotage his tour.

He wrote in his blog: "I am shocked and covered in disbelief at being privy personally to a design by certain sections of the media and the fraternity to bring down this show. To kill it, to malign and write it off. I have on several occasions spoken of a bias that exists for no reason whatsoever."

Bachchan adds, so all readers of blog and well wishers and fans, you are warned and asked to be prepared for negativity by design to come your way. Not just for the show. In other many aspects too.

Bachchan is on the Unforgetable world tour with son Abhishek, daughter-in-law Aishwarya and Bollywood actors Preity Zinta and Ritesh Deshmukh. The tour kicked off from Toronto and will also see these stars travel to US and England.

Though Big B has not named anyone in particular the blog has given way to speculations.

"There may be a business point of view to the whole conspiracy or it could be something else," said Bobby Khan, Chairman, Bobby Khan Holdings.

Before the start of the tour Bachchan was asked at a media conference about a clash with Shah Rukh Khan who is also touring at the same time. He had said that anyone could tour whenever they wanted and there was no competition.

The answers to the alleged conspirator could well lie in Bachchan's next blog entry.
