Central Graeme Swann

Recently-retired England spinner Graeme Swann has attacked "some low forms of journalism" for "preying" on his 90-year-old grandmother.

Mina Swann's comments to Newcastle's Journal newspaper were widely quoted in the English and Australian media.

England batsman Kevin Pietersen refused to be drawn into the Graeme Swann story on Tuesday and distanced himself from speculation suggesting the retired bowler's team-mate remarks were referring to him.

"I'm not giving any energy to what happened yesterday," he said at a press conference ahead of the fourth Ashes Test in Melbourne.

"The only energy that I've got on this tour left in me is for Melbourne on the 26th, training today, training tomorrow and Sydney.

"My interest levels in yesterday are less than zero."

Graeme Swann has told his former England captain not to "jump to conclusions" after Michael Vaughan claimed Swann's post-retirement comments were a mistake.

Former England captain Michael Vaughan said he agrees with former team mate Graeme Swann that "some players are getting ahead of themselves", but inferred the timing of his comments was a mistake.

Graeme Swann has attempted to distance himself from a report in The Telegraph which alleged the retiring cricketer had made a "barely disguised swipe" at his fellow English cricketers.

Swann took aim at the journalist who wrote the story, saying "making stuff up sells papers I suppose".

Graeme Swann will be missed by both Nottinghamshire and England, according to the county's Director of Cricket, Mick Newell.

The spinner announced his retirement from all forms of cricket today with immediate effect.

Newell says Swann was a great character to have around the dressing room, but he will not miss watching him bat, as he claims it caused his grey hair!

The Director of Cricket at Nottinghamshire County Cricket Club believes the 'irreplaceable' nature of Graeme Swann is one of the reasons the spinner was selected for the first three games in Australia, despite his claims today that he isn't fully fit.

Graeme Swann's announcement that he is to retire from first class cricket has received mixed reaction. Swann has said his arm has not felt 'quite right' since his operation earlier this year. Some have criticised him for playing in this series if he knew he was not 100% fit.

Mick Newell says the selectors probably had no choice but to select him, because has has previously been 'irreplaceable'.

Cricketer Graeme Swann's snap retirement from the England team during the Ashes tour has drawn shocked reactions on Twitter, with Piers Morgan calling the move "embarrassing" and saying the Australian team "must be laughing their heads off".

Former England batsman and bowler Paul Collingwood said "I can't believe it", while commentator Jonathan Agnew said the move was "unexpected".

Swann has left the England team after they suffered three successive defeats on their Ashes tour to Australia.
