Editing Haydock (section)

==Governance==
Haydock was a township in the parish of [[Winwick, Cheshire|Winwick]] before being made a [[civil parish]] in 1866. The village was in the [[poor law union]] of [[Warrington]] in the 19th century before being created an [[Urban district (Great Britain and Ireland)|urban district]] in 1894.

Between 1830 and 1983 Haydock was part of the [[Newton (UK Parliament constituency)|Newton parliamentary constituency]]. In 1983 the Newton constituency, containing [[Golborne]], [[Irlam]] and [[Newton-le-Willows]] urban districts, and [[Warrington]] Rural District (containing Winwick), was divided,<ref name="Order1983">Parliamentary Constituencies (England) Order 1983 (S.I. 1983 No. 417)</ref> and Haydock, along with Newton-le-Willows, was incorporated into the [[St Helens North (UK Parliament constituency)|St Helens North Constituency]].<ref name="Order1983"/>

The traditional Haydock boundary encapsulated part of [[Blackbrook, St Helens|Blackbrook]], and part of Haydock Park (the northern perimeter made up by Garswood Park and the course of Clipsley Brook). The western boundary was Blackbrook, downstream of its confluence with Clipsley Brook, while the eastern boundary was composed of Sandy Lane and Newton Lane as far south as Dean Dam and Cowhey Dam.<ref>{{cite web|url=http://www.visionofbritain.org.uk/unit/10354614/boundary|title=Haydock Tn/CP through time {{!}} Boundary Map of Haydock Tn/CP|work=A vision of Britain through time|publisher=University of Portsmouth and others|year=2009|access-date=2010-12-10}}</ref> Portions of the old Haydock Parish are now within the modern Newton-le-Willows for the purposes of local administration and postal services, and utilise 01942 dial codes due to their proximity to those local exchanges.

Changing local administrative boundaries in 1933 transferred 16 acres of land to the Ashton-in-Makerfield civil parish<ref>{{cite web|url=http://www.visionofbritain.org.uk/unit/10354614/relationships|title=Haydock Tn/CP through time {{!}} Administrative history of Parish-level Unit: hierarchies, boundaries|work=A vision of Britain through time|publisher=University of Portsmouth and others|year=2009|access-date=2010-12-10}}</ref> which is, today, one of the seven parishes of St Helens.

Further ward profile changes in 2007 to those made in 2004 extended the Haydock ward,<ref>{{cite web|url=http://www.neighbourhood.statistics.gov.uk/dissemination/LeadAreaSearch.do?a=7&c=Wigan&d=13&r=1&o=1&i=1001&m=0&s=1294099400072&enc=1&areaSearchText=Haydock&areaSearchType=14&extendedList=false&searchAreas=|title=Area: Haydock (Ward)|publisher=Office for National Statistics}}</ref> reducing the Billinge and Seneley Green Ward. Part of the Haydock Royal Air Force site housing development, including Slag Lane along with a section of Liverpool Road, was appropriated to Haydock and Blackbrook wards respectively, for electoral purposes. Seneley Green Parish Council continue to collect the parish precept and have authority on planning issues.

In January 2009 Haydock as part of the St Helens Metropolitan Borough agreed to form the [[Liverpool City Region]], a [[Multi-Area Agreements|Multi-Area Agreement]] enjoying greater devolved powers than local government. In 2014 this was established in statute as the [[Liverpool City Region Combined Authority]] covering the metropolitan county of Merseyside and the adjacent Borough of Halton.
