Judges singled out the paper's disability series – which was written entirely by Disabled people – and its coverage of the Partygate scandal for special mention.
With writers including DR UK's media and communications lead Anna Morell, the disability series was edited by Rachel Charlton-Dailey, founder of The UnWritten – a platform for Disabled people to tell their stories authentically.
The week-long coverage, under the banner Disabled Britain: Doing it for Ourselves, covered issues ranging from social attitudes to politics and social media.
DR UK's Head of Policy, Fazilet Hadi, said: "We look forward to the day when the voices of Disabled people are part of the daily national conversation. However, the Daily Mirror's coverage has educated many people about a range of important issues and helped shatter some stereotypes and myths. Congratulations to Anna and the other contributors."
