Michelle O’Neill (née Doris), Irish politician who serves as deputy First Minister of Northern Ireland between 2020 and 2022, is born in Fermoy, County Cork, Republic of Ireland, on January 10, 1977. She has been serving as Vice President of Sinn Féin since 2018 and is the Member of the Legislative Assembly (MLA) for Mid Ulster since 2007.

O’Neill comes from an Irish republican family in Clonoe, County Tyrone, Northern Ireland. Her father, Brendan Doris, was a Provisional Irish Republican Army (IRA) prisoner and Sinn Féin councillor. Her uncle, Paul Doris, is a former national president of the Irish Northern Aid Committee (NORAID). A cousin, Tony Doris, was one of three IRA members killed by the British Army‘s Special Air Service (SAS) in the Coagh ambush in 1991. Another cousin, IRA volunteer Gareth Malachy Doris, was shot and wounded during the 1997 Coalisland attack.

After the death of Brendan Doris in 2006, Martin McGuinness pays tribute to the Doris family as “a well-known and respected republican family [who] have played a significant role in the republican struggle for many years.”

O’Neill attends St. Patrick’s Girls’ Academy, a Catholic grammar school in Dungannon, County Tyrone. She subsequently begins to train as an accounting technician, before pursuing a political career.

O’Neill becomes involved in republican politics in her teens, assisting her father with constituency work in his role as a Dungannon councillor. She joins Sinn Féin after the Good Friday Agreement in 1998, at the age of 21, and starts working as an advisor to Francie Molloy in the Northern Ireland Assembly, holding this role until 2005.

O’Neill serves on the Dungannon and South Tyrone Borough Council from 2005 to 2011. She serves as the first female Mayor of Dungannon and South Tyrone from 2010 to 2011. In the 2007 Northern Ireland Assembly election she is elected to represent Mid Ulster in the Northern Ireland Assembly. In 2011, she is appointed to the Northern Ireland Executive by deputy First Minister Martin McGuinness as Minister for Agriculture and Rural Development. In 2016, she is promoted to Minister of Health. In January 2020, she becomes deputy First Minister of Northern Ireland after the New Decade, New Approach (NDNA) agreement restores the power sharing executive.

O’Neill automatically relinquishes her office following Paul Givan‘s resignation as first minister on February 3, 2022. Sinn Féin becomes the largest party after the 2022 Northern Ireland Assembly election, putting O’Neill in line to become the First Minister of Northern Ireland, and the Democratic Unionist Party (DUP) leader to become the deputy First Minister of Northern Ireland. However, she remains to be officially sworn in as First Minister because, as part of its opposition to the Northern Ireland Protocol, the DUP has refused to nominate a deputy First minister and there is therefore no functioning executive of Northern Ireland.

In August 2022, O’Neill is asked in a BBC interview whether it was right during the Troubles for the Provisional IRA “to engage in violent resistance to British rule.” She is criticised for her response, “I think at the time there was no alternative, but now thankfully we have an alternative to conflict, and that is the Good Friday Agreement – that is why it’s so precious to us all.”

In May 2023, O’Neill attends the coronation of King Charles, saying, “Well obviously I wanted to be here. We live in changing times, and it was the respectful thing to do, to show respect and to be here for all those people at home, who I had said I would be a first minister for all. Attendance here is about honouring that and fulfilling my promise.”

Under O’Neill’s leadership, Sinn Fein has led most opinion polls for the next United Kingdom general election.
