Andrew Gardner has called on Islington-based Shaw PR to help redress damage caused to his reputation following the trial for the death of 27-year-old Nina Longe, which he feels was unfairly reported in the press.
Gardner was cleared of murdering Longe after the court heard she committed suicide.
But former hospital worker Gardner claims the media failed to report his innocence, instead focusing on the prosecuting lawyer's accusations, and now wants to clear the record.
Gardner told PRWeek: 'I'm hoping to get my side of the story out and hopefully I can then try and resurrect my life.
'I'm also doing this for my family - my son was put through the wringer when he was only 15-years-old.'
Shaw PR will waive fees to help Gardner in his endeavour.
Agency MD George Shaw said the firm will be calling on the Press Complaints Commission in its mission to ensure the media gives fair representation to both defence and prosecution cases in the future.
Shaw PR's appointment marks Gardner's second PR hire. His lawyer during the trial took on PRHQ founder Kizzi Kkwocha last year - also on a no-fee basis - but engaging the media was abandoned as reports sparked controversy, suggesting Gardner wanted to make money from the case, a claim which he denied.
