Hodder Moa Beckett managing director and publisher Kevin Chapman said the book Balance Of Power had undergone the regular legal checks.

In the book written by journalist Richard Boock, Fleming had named sports promoter-turned businessman Khetrapal as the one to approach him to join the match-fixing syndicate in 1999.

"I am certainly considering filing a defamation suit but I cannot do so only on the basis of media reports," Khetrapal said.
"We will go through the book and what is written in it and would take appropriate decision in a couple of days," Khetrapal said.
