The Equality Party (French: "Parti Égalité" ) was a political party in Quebec, Canada, that promoted the use of English in Quebec on an equal basis with French.
 Four Equality Party members were elected to Quebec's National Assembly in 1989, as part of an anglophone reaction to changes made by the governing Liberals to Quebec's language law.
 The party had no success in subsequent elections, and stopped organizing after the 2003 Quebec election.
Party of Construction and Labour (in French: "Parti de la construction et du travail") is a political party in Benin.
 Its youth wing is known as "Forum International de la Jeunesse".
Krishak Mukti Sangram Samiti (KMSS) is a peasant organisation based in Assam.
 Formed by the RTI activist Akhil Gogoi in 2005, the organisation works on a diverse range of issues from Public Distribution System (PDS) thefts, non-implementation of National Rural Employment Guarantee Act (NREGA), land rights, governmental and corporate corruption, Right to Information Act (RTI) and construction of big dams in fragile seismic territories of north east India.
 The organisation came to national lime light after it joined the crusade against corruption under the leadership of Gandhian activist Anna Hazare.
 However, KMSS broke with India Against Corruption campaign after some of the IAC members decided to form a political party.
 Explaining the reasons to resign from IAC, KMSS General Secretary Akhil Gogoi said that the support IAC had received was only for building up a strong and sustained mass movement against rampant corruption, and not floating an election-centred political party.
Tamil Arasu Kazhagam (Association for Tamil Autonomy) (Tamil: தமிழ் அரசு கழகம் ) was an Indian political party founded by M. P. Sivagnanam (Ma.
 Po.
 Si) in Tamil Nadu.
 It was established as an association in 1946.
 Its goals were to pressurize the Indian National Congress Government of the Madras Presidency to increase the use of Tamil in administration and education, to create an autonomous Tamil state out of a composite Madras Presidency and to soften the pro-Hindi stance of the Congress.
 The association was allied with the Congress during 1946-54 and worked against the Dravidian Movement.
 However, it grew closer to the Dravida Munnetra Kazhagam (DMK) over time.
 During 1946-54, Sivagnanam was a member of the Congress.
 He left the Congress in 1954 and turned the Tamil Arasu Kazhagam into an independent political party.
 During 1957-60, it was involved in various protests over the drawing of state boundaries when Andhra Pradesh split from the composite Madras State.
 It eventually became a part of DMK's electoral alliance in the 1967 assembly elections.
 It was also involved in the movements to change the name of the state from Madras State to Tamil Nadu and to promote the use of Tamil over Sanskrit for conducting "Archanai" (Offerings to God) in Hindu temples.
 In the 1967 elections, two candidates of the party (including Sivagnanam) were elected to the assembly contesting under DMK's "Rising Sun" Symbol.
 The party was also an DMK ally in the 1971 assembly elections.
 In 1972, it opposed the DMK chief minister M. Karunanidhi's decision to scrap prohibition laws and switched its allegiance to DMK's splinter group - the M. G. Ramachandran led Anna Dravida Munnetra Kazhagam (ADMK).
 The party did not directly contest in elections after 1971 and Sivagnanam was nominated to the Tamil Nadu Legislative Council in 1972.
 He remained as the member of the legislative council till its disbandment in 1986.
 The party stopped functioning after Sivagnanam's death in 1995.
The Best Party (Icelandic: "Besti flokkurinn" ) was an Icelandic political party founded by Jón Gnarr on 16 November 2009.

Dagenham ( ) is a large suburb of east London, England.
 In the London Borough of Barking and Dagenham, it is 11.5 miles (18.5 km) east of Charing Cross and 9.5 miles (15.2 km) east of the City of London.
 Historically in Essex, it was an agrarian village and remained mostly undeveloped until 1921, when the London County Council began construction of the large Becontree estate.
 The population of the area significantly increased in the 20th century, with the parish of Dagenham becoming an urban district in 1926 and a municipal borough in 1938.
 It has formed part of Greater London since 1965 and is a predominantly residential area, with some areas of declining industrial activity, including the Ford Dagenham plant.
 The southern part of Dagenham, adjacent to the River Thames, forms part of the London Riverside section of the Thames Gateway redevelopment area.
The Thames Gateway Bridge was a proposed crossing over the River Thames in east London, England.
 It was first mooted in the 1970s but never came to fruition.
 In November 2008, Boris Johnson, the then Mayor of London, formally cancelled the entire £500 million scheme.
The Mark Morris Memorial Bridge (locally called the North Bridge) is a 2 lane truss bridge across the Mississippi River in the United States.
 It connects the cities of Clinton, Iowa and Fulton, Illinois.
 The bridge may also be known as the Lyons-Fulton Bridge, which was the name of a predecessor bridge and the name listed on the USGS topographical map.
 The town of Lyons, Iowa, was annexed to Clinton in 1895, but the north end of the city is still referred to as Lyons.
 The bridge is the terminus of both Iowa Highway 136 and Illinois Route 136.
 The 1975 bridge was named in memory Mark Morris, a long time member of the City of Clinton Bridge Commission who died in 1972.
 Morris was instrumental in the construction of the 1975 bridge and the City of Clinton Bridge Commission named it in his honor.
 The bridge was opened in January 1975, replacing an older span upstream that once carried the Lincoln Highway, U.S. Route 30.)
 In 1982, Iowa DOT announced that it would be removing a 20 cent toll from the Gateway Bridge and the Mark Morris bridge beginning January 1983.
 Iowa and Illinois agreed to split responsibility for the maintenance of the two bridges with Iowa maintaining the Mark Morris bridge and Illinois the Gateway bridge.
VLOTT is a minor Belgian right-wing liberal or fortuynist political party.
 Its title, "VLOTT", is a backronym for "Flemish, Liberal, Independent, Tolerant, Transparent" ("Vlaams, Liberaal, Onafhankelijk, Tolerant, Transparant").
 It was founded on 23 November 2005 by ex-Open VLD member Hugo Coveliers.
 It participated in a list-cartel with the Vlaams Belang in the October 2006 Antwerp municipal elections and in selected provincial, municipal and district elections elsewhere in Flanders.
 Despite the popularity of their founder in Antwerp (13 623 personal votes, 3rd most popular) the shared effort of the cartel-partners did only result in a small 0.5 percent win, with no extra seat in the city-council.
 In 2007, VLOTT did not participate in the general elections, but their candidates appeared as independents on the Vlaams Belang ballots.
 Only founder Hugo Coveliers was elected to the Belgian Senate.
 After Coveliers withdrawal from active politics early 2012 Vlaams Belang stopped its cooperation with the party.
