Corrie won the 'Broadcast of the Year' gong at last night's ceremony, which celebrated those who have made a positive impact on the lives of lesbian, gay and bisexual people in the past 12 months.
The Weatherfield show has featured its first ever lesbian storyline this year, focusing on long-standing character Sophie Webster's (Brooke Vincent) blossoming romance with best friend Sian Powers (Sacha Parkinson).
Corrie had faced competition from rival soaps EastEnders and Emmerdale in the category, as well as factual Channel 4 programmes The Sex Education Show and Dispatches: Africa's Last Taboo.
Meanwhile, Partridge won the 'Entertainer of the Year' prize for his role as Walford's Christian Clarke, who has found love with Syed Masood (Marc Elliott) on screen despite the fierce objections of the practising Muslim's family.
According to Pink News, Partridge paid tribute to EastEnders' former series story producer Dominic Treadwell-Collins at yesterday's event, praising him for managing to "tell a gay story at 7.30 in the evening".
The 39-year-old had been nominated in the 'Entertainer' category alongside stars including Colin Firth and Glee's Jane Lynch.
Others who were recognised on the night included rugby star Gareth Thomas, who was named 'Hero of the Year' for his decision to speak publicly about his homosexuality.
Speaking of the winners, Stonewall's chief executive Ben Summerskill commented: "This has been a landmark year. All three major soaps have featured compelling depictions of lesbian and gay characters. All three main parties have made gay equality a central, vote-winning election issue. And rugby now has its first openly gay professional player. We're proud to have seen all these successes of modern Britain reflected at the Stonewall Awards ceremony."
