A memorial service for campaigning journalist Adrian Sudbury, the "baldy blogger" who died of leukaemia in August, is being held today at Sheffield Cathedral. Adrian, 27, a reporter with Trinity Mirror's Huddersfield Examiner, spent the last few months of his life raising awareness of bone marrow donation in a campaign, including taking a petition with 11,000 signatures to Downing Street, which captured the attention of the world's media. The Examiner is carrying a live video feed of the celebration of Adrian's life and work from Sheffield Cathedral on its website from 2pm.
