England captain Andrew Strauss voiced his "outrage" at comments made by Pakistan cricket chief Ijaz Butt accusing his side of corruption as it was confirmed the two remaining one-day internationals between the countries would go ahead as scheduled.
Strauss's comments came after Butt had fanned the flames of the corruption allegations overshadowing the series by accusing England players of match-fixing in the third one-dayer across London at The Oval on Friday.
Butt's comments were branded "wholly irresponsible and without foundation" by a separate England and Wales Cricket Board (ECB) statement.
Strauss, speaking on behalf of the England team, threatened Butt with possible legal action, in a statement that said: "We would like to express our surprise, dismay and outrage at the comments made by Mr. Butt yesterday [Sunday].
"We are deeply concerned and disappointed that our integrity as cricketers has been brought into question. We refute these allegations completely and will be working closely with the ECB to explore all legal options open to us.
"Under the circumstances, we have strong misgivings about continuing to play the last two games of the current series and urge the Pakistani team and management to distance themselves from Mr. Butt's allegations.
"We do, however, recognise our responsibilities to the game of cricket, and in particular to the cricket-loving public in this country, and will therefore endeavour to fulfil these fixtures to the best of our ability," he added.
Strauss's statement was made public shortly before the toss in the fourth one-day international here at Lord's and ahead of the series finale at Hampshire's Rose Bowl ground on Wednesday.
The opening batsman, speaking after the toss at Lord's, told Sky Sports: "It's been a difficult 24 hours for us, there's no doubt about that.
Asked if Butt's remarks soured relations between the teams, Strauss added: "I don't know about that.
"It's one of those situations where everything is a bit raw and emotional and there is a responsibility on all 22 players that it's the cricket that does the talking."
However, Sky reported there had been an altercation in the Lord's nets between England batsman Jonathan Trott and Pakistan seamer Wahab Riaz -- one of four Pakistan players interviewed by British police.
The ECB statement said: "Mr. Butt's comments were wholly irresponsible and completely without foundation," but added "it would set a dangerous precedent to call off a tour based on the misguided and inaccurate remarks made by one individual".
Pakistan Cricket Board chairman (PCB) Butt's comments came after fresh corruption claims against Pakistan emerged on Saturday, with Britain's Sun tabloid claiming to have been made aware of details of Pakistan's innings before Friday's match had got underway.
The paper informed the International Cricket Council (ICC) which then watched as scoring patterns in two suspect overs emerged as predicted, the Sun said.
But the overall result of the match, which Pakistan won by 23 runs, was not believed to be fixed, the report added.
Pakistan's Salman Butt, Mohammad Aamer and Mohammad Asif have all been questioned by British police over an alleged plot to bowl deliberate no-balls during last month's Test at Lord's.
All the trio, as well as Riaz, have denied any wrongdoing.
