Alan Henry Brooke, 3rd Viscount Brookeborough, KG, KStJ (born 30th June 1952), is a Northern Irish peer and landowner. He is one of the 92 hereditary peers who remain, for life, in the House of Lords, and is the current Lord Lieutenant of Fermanagh, sitting as a crossbencher.
Lord Brookeborough was educated at Harrow School, Millfield, and the Royal Agricultural College, Cirencester.
He joined the British Army in 1971, being commissioned into the 17th/21st Lancers. In 1977 he transferred to the Ulster Defence Regiment (UDR), which was to become the Royal Irish Regiment in 1992. He was promoted to Lieutenant-Colonel in 1993, and became Honorary Colonel of the 4th/5th Battalion, Royal Irish Rangers, in 1997.
Lord Brookeborough (known to his family and friends as Alan Brooke or Alan Brookeborough) married Janet Elizabeth Cooke (daughter of J.P. Cooke, of Doagh), now Viscountess Brookeborough, in 1980. They farm the 1,000 acres Colebrooke Estate, just outside Brookeborough in County Fermanagh, Northern Ireland. The centre of the estate is Colebrooke Park, an early 19th-century neo-Classical country house that is the ancestral seat of the Brooke family.
Brooke succeeded his father as the 3rd Viscount Brookeborough in 1987. Although he lost his automatic right to a seat in the House of Lords, with all other hereditary peers after the passage of the House of Lords Act 1999, Lord Brookeborough remained in the House as an elected crossbench hereditary peer.
He has been a Lord-in-waiting to The Queen since 1997. He is President of the Co. Fermanagh Unionist Association and was appointed as an independent member of the Northern Ireland Policing Board in 2001. The Lord Brookeborough has represented The Queen as HM's Lord-in-Waiting, instead of The Prince of Wales and Duchess of Cornwall, on the arrival of the U.S. President, Barack Obama, and First Lady Michelle Obama to the United Kingdom on their official state visit, on 24 May 2011.
