IRA veterans 'could have crucial Bloody Sunday evidence'

A lawyer acting for five men who were members of the Official IRA in 1972 has come forward to the Bloody Sunday inquiry offering a "positive and possibly very, very significant impact" on proceedings.

Barrister Gareth Purvis made a preliminary approach on behalf of the five, said to include the gunman witnessed by retired Catholic Bishop of Derry, Dr Edward Daly, shooting from a pistol that day almost three decades ago.
