The reports saying that  Margaret Thatcher government in Britain had advised India in executing Operation Blue Star through its Special Air Service (SAS) are also mentioned in a book written by one of the founders of the Research and Analysis Wing Bahukutumbi Raman. His write-ups were first published in 2007.

In this book he had stated that two officers of Britain’s Military Intelligence 5 (MI5) had visited the Golden Temple as tourists and advised Prime Minister Indira Gandhi to be patient. They had also advised her to avoid action or use of police as suggested by the Indian intelligence agencies at that time.

They advised her to be patient for some weeks instead of taking any impulsive action which might produce certain adverse circumstances. They had also advised her to use the police or central paramilitary forces instead of the Army if any immediate action was found necessary,
