Stephen E Diggle (born 7 May 1955) is an English musician best known as a guitarist and later lead vocalist in the punk band Buzzcocks. In 1976, Diggle was recruited as a bassist for Buzzcocks, playing bass on the Spiral Scratch EP (1977). Following the departure of original lead vocalist Howard Devoto soon after, Diggle switched to guitar while Pete Shelley became lead vocalist. He became a member of the band's classic lineup, playing on Buzzcocks' first three albums as well as their acclaimed compilation Singles Going Steady (1979). Following the group's breakup in 1981, Diggle formed a new band, Flag of Convenience in 1982 before disbanding it in 1989 when Buzzcocks re-formed. Following Shelley's death in 2018, Diggle has become the band's new lead vocalist. With the release of Sonics in the Soul (2022), he is the only member to have played on all of the group's albums and EPs. He has also released four solo albums between 2000 and 2016.
