England squad warned about Twitter behaviour

England's cricketers have been warned to be more careful when using Twitter.

In the past week, England players Kevin Pietersen and Dimitri Mascarenhas have been fined for using obscenities in messages criticising selectors.

And while the England and Wales Cricket Board (ECB) will not stop players tweeting, managing director Hugh Morris said controls would be introduced.

"With freedom of speech comes responsibility. It must be used that way," Morris told BBC Radio 5 live.

While praising Twitter as a means by which players can keep in contact with supporters, Morris confirmed that a policy managing usage would be in place in time for this winter's Ashes series in Australia.

"We've had some good discussions with the players' representatives over this over the last few weeks and that's exactly the type of way we will look to manage Twitter and other social networking sites going forward," added Morris.

"The specific wording is yet to be agreed between ourselves and the Professional Cricketers' Association but certainly there will be some management around the use of Twitter. It's a good opportunity but it needs to be used in the right way."

The ECB has been forced to act after two incidents in the past fortnight.

On 31 August, former captain Pietersen broke the news of his omission from England's one-day squad with a tweet containing an expletive, while on 5 September Mascarenhas launched a personal attack on chairman of selectors Geoff Miller.

Pietersen, who received an undisclosed fine, said his message was only intended for friends, while Mascarenhas, fined £1,000, admitted a late night conversation had "got out of control". Both players subsequently apologised.

Last October, England team-mate Tim Bresnan was warned about his future conduct after swearing in a tweet, and earlier this summer Yorkshire's former England Under-19s captain Azeem Rafiq received a one-month ban for a similar offence.

Australian cricketer Phillip Hughes was also criticised for using Twitter to announce he had been dropped from Australia's Test side last summer.

29 cricketers suspected of spot-fixing in IPL 2

In a startling revelation, 29 cricketers are suspected of spot-fixing in the second edition of the Indian Premier League (IPL) in South Africa last year.

The list, compiled by the International Cricket Council's Anti-Corruption and Security Unit, includes some high-profile names but none from England or Pakistan. Pakistan's players did not take part in the Twenty20 tournament.

'Some betting patterns were very suspicious at IPL 2,' Sunday Times reported.

There have been long-standing concerns about the integrity of IPL, whose commissioner Lalit Modi is suspended on corruption charges.

Earlier, three Pakistani players Salman Butt, Mohammad Asif and Mohammad Amir were suspended by the ICC after their alleged involvement in the spot-fixing controversy during the fourth Test against England at Lords.
