Mithali had recently accused the English team of being foul-mouthed and speaking ''rot'' in the two-match Test series, which the Indians won 1-0.
The ECB, however, denied any sledging incident during the series and rejected the claims made by the Indian skipper.''England takes pride in playing cricket within the spirit of the game and the series against India was no different,'' ECB said in a statement here.
''As far as England were concerned it was played in a friendly and competitive way. At no point did any England player breach the ICC Code of Conduct nor were any players approached by the umpires throughout the series,'' it added.
Mithali had claimed that the English players sledged in the second Test forcing her team to retaliate in a similar manner during the match.
The Indian eves were routed 1-4 in the ODI series before they won the Test series to end the tour on a high.
