Rio Ferdinand is to be left out of England's Euro 2012 squad when it is unveiled by new manager Roy Hodgson this afternoon.

Hodgson is believed to have spoken to the Manchester United defender on Tuesday and told him he would not be going to Poland and Ukraine this summer. Ferdinand has made no comment on the matter.

Speculation is rife this morning that his troubled relationship with John Terry, rather than recent injuries, is behind Hodgson's decision, although on Friday Sir Alex Ferguson said it was impossible for Ferdinand to play twice in four days.

As a similarly packed schedule would have to be navigated at the European Championships, Hodgson may well have concluded that he cannot take the risk of managing one of his senior players through a tournament of such significance.

The news will come as a blow to Ferdinand, who had declared his intention to make himself available this summer, despite obvious complications over his relationship with John Terry.

Terry will face a court case later this year after being charged with making comments of a racist nature to Ferdinand's brother Anton during the Blues Premier League encounter with QPR at Loftus Road last October. Terry denies the charges.

It is thought Terry will be part of the England squad, along with club colleague Frank Lampard.

Hodgson's firm decision about Ferdinand appears to signal the end of his 81-cap England career. Ferdinand last featured for his country in the Euro 2012 qualifier against Switzerland in June 2011, although he was selected for the friendly against Holland the following August which was postponed due to the London riots and it is not the only bold decision Hodgson has taken.

Hodgson has now taken the even more significant decision to scrap next week's planned training camp in Spain - giving rise to more speculation that the Terry case has already caused significant divisions among the squad.
