Relatives of those killed on Bloody Sunday are expected to return to the Saville Inquiry today, 24 hours after their walkout.
They left the hearing as a policeman gave his evidence to the Inquiry from behind a wooden screen erected around the witness box.
Twenty-one serving or former police officers propose to give evidence the same way even though they are named at the Inquiry.
The families who walked out of the Guildhall in Derry yesterday say the screening makes a mockery of Tony Blair’s promise to hold an open and transparent public Inquiry.
