Van Haersma Buma was the secretary of the Christian Democratic Appeal in The Hague and a member of the executive committee of the Christian Democratic Appeal in the province of South Holland in the late 1990s. From January to June 2002 he was a member of the municipal council of Voorburg and since May 2002 he is a member of the Dutch House of Representatives. He became the party's spokesman on judicial affairs and is known for his law and order approach. From 2007 to 2010 he was the secretary of the Christian Democratic Appeal parliamentary group in the House of Representatives.
After the 2017 Dutch general election, the CDA formed the Third Rutte cabinet alongside the VVD, D66 and CU. However Van Haersma Buma remained in the House of Representatives as parliamentary leader instead of entering the government.
Buma was nominated as Mayor of Leeuwarden by the city's municipal council on 16 May 2019.[7] He was succeeded by Pieter Heerma as parliamentary leader in the House of Representatives on 21 May.[8] On 26 August 2019 Buma was appointed Mayor of Leeuwarden.[9]
^The family Van Haersma Buma is a branch of the old Frisian Buma dynasty, dating back to foremother Jouck Goris Buma, who married Wijbe Fennes in 1646. Bernhardus Buma (1770–1838) was burgomaster of Leeuwarden. His son, Wiardus Willem Buma married Maria de With (1803–1878), who was a daughter of Catharina van Haersma (1764–1824). When the Van Haersma family became extinct, their son Sijbrand Buma (1830–1886) bought the right to add the Van Haersma name to his own in 1870, starting the Van Haersma Buma branch of the Buma family (the other branch is the Hopperus Buma branch). Sybrand usually went by "Buma" in his public life.[1]
