Ian Milne, Irish republican politician from Northern Ireland, is born in Bellaghy, County Londonderry, April 8, 1954.

Milne joins the Official Irish Republican Army-linked Fianna Éireann youth group soon after its formation, but the following year moves to join the Provisional Irish Republican Army. He is gaoled in 1971, after explosives go off in a car in which he is traveling. He is imprisoned in the Crumlin Road Gaol, but escapes in January 1973. The following year, he is arrested in the Republic of Ireland after stealing a Garda car and is sentenced to five years in Portlaoise Prison. However, he again escapes, and remains an active paramilitary based in Northern Ireland.

During the mid-1970s, the Royal Ulster Constabulary (RUC) describes Milne as one of its three “most wanted.” In 1977, he is arrested and sentenced to life for killing a British soldier. Serving time at Long Kesh Detention Centre, he participates in the blanket protest. He is released in 1992.

At the 2005 Northern Ireland local elections, Milne is elected to Magherafelt District Council for Sinn Féin, and he holds his seat in the 2011 elections. While on the council, he spends a period as chairman. In 2013, he is co-opted to the Northern Ireland Assembly in Mid Ulster, replacing Francie Molloy. He is elected to the Northern Ireland Assembly for Mid Ulster at the 2016 Northern Ireland Assembly election.

In September 2017 Milne is served civil writs for his alleged involvement in the murder of Jimmy Speer on November 9, 1976.

In December 2018, Milne resigns as Member of the Legislative Assembly (MLA) to seek reelection to local government. He is elected to Mid Ulster District Council in 2019 and continues to hold this position as of 2023.
