London: The England and Wales Cricket Board has threatened to take legal action against Pakistan Cricket Board chairman Ejaz Butt unless he apologises for accusing England of losing a game.
Butt said he had heard from bookmakers that England had been paid to lose Friday`s third one-day game at The Oval.
England, who lost the game by 23 runs, has denied the allegations, The BBC reports.
ECB chief David Collier said: "We are looking for an apology. If it does not come we`ll look at other options. Clearly we will seek advice but there are quite strong laws of defamation. You can`t impugn someone`s integrity without having proper evidence."
"To date I can say that we have received zero evidence of anything having influenced any England player," he added.
The International Cricket Council is also looking into Pakistan`s performance in last week`s one-day game at The Oval after receiving reports about "scoring patterns" during their innings.
