Question: What was the name of the series of five yachts owned by the man that was Prime Minister of the United Kingdom from 1970 to 1974?
Context: Colonel Patrick Roland John (born Roseau, 7 January 1938) was the Prime Minister of Dominica as well as the Premier of Dominica.  During his premiership Dominica gained independence from the United Kingdom and he became the first Prime Minister of Dominica.  He was leader of the Waterfront and Allied Workers' Union and mayor of Roseau before being elected to the legislature in 1970.  He took on prime ministerial duties in 1974 following the resignation of Edward Oliver LeBlanc.  After mass protest forced him to resign, John unsuccessfully attempted to overthrow the government of Prime Minister Eugenia Charles with the backing of white supremacist groups (in what became dubbed "Operation Red Dog").  As a result, he was jailed for twelve years, of which he served only five years. The Prime Minister's Official Spokesperson or alternatively Prime Minister's Official Spokesman/Spokeswoman is a position in the United Kingdom's Civil Service, located in the Prime Minister's Office in 10 Downing Street and used by the British Prime Minister to convey information to the public.  The Prime Minister's Official Spokesperson usually addresses a small group of press and media correspondents, known as lobby correspondents, each morning to deliver statements on current events on behalf of the Prime Minister. Dubai is the name of a yacht currently owned by Sheikh Mohammed bin Rashid Al Maktoum, the ruler of the Emirate of Dubai and the Prime Minister of the United Arab Emirates.  This vessel is 162 m long, is the third largest yacht in the world after "Azzam" and "Eclipse".  Including crew it can hold more than 115 guests on it.  Designed by Andrew Winch, with interior design by Platinum Yachts, it cost US$400 million.  The construction was originally planned for Prince Jefri Bolkiah of Brunei before 1996 as a joint project between Blohm + Voss and Lurssen shipyards.  Progress stopped until 2001 when the hull was acquired by Platinum Yachts for Sheikh Mohammed bin Rashid Al Maktoum.  The yacht, previously named Platinum, Panhandle and Golden Star, was then renamed Dubai. The Prime Minister of Northern Ireland was the head of the Government of Northern Ireland between 1921 and 1972.  No such office was provided for in the Government of Ireland Act 1920, however the Lord Lieutenant, as with Governors-General in other Westminster Systems such as in Canada, chose to appoint someone to head the executive even though no such post existed in statute law.  The office-holder assumed the title "Prime Minister" to draw parallels with the Prime Minister of the United Kingdom.  On the advice of the new Prime Minister, the Lord Lieutenant then created the "Department of the Prime Minister".  The office of Prime Minister of Northern Ireland was abolished in 1972, along with the contemporary government, when direct rule of Northern Ireland was transferred to London. Morning Cloud was the name given by the British politician Edward Heath to a series of five yachts which he owned between 1969 and 1983. The Prime Minister of the United Kingdom is the head of the Government of the United Kingdom, and chairs Cabinet meetings.  There is no specific date when the office of Prime Minister first appeared, as the role was not created but rather evolved over a period of time.  The term was used in the House of Commons in 1805 and it was certainly in parliamentary use by the 1880s, and in 1905 the post of Prime Minister was officially given recognition in the order of precedence.  Modern historians generally consider Sir Robert Walpole, who led the government of Great Britain from 1721 to 1742, as the first Prime Minister.  Walpole is also the longest-serving Prime Minister by this definition.  However, Sir Henry Campbell-Bannerman was the first Prime Minister and Margaret Thatcher the longest-serving Prime Minister to have been officially referred to as such. This is a list of royal yachts of the United Kingdom.  There have been 84 royal yachts since the restoration of the monarchy in 1660.  King Charles II had 25 royal yachts and five were simultaneously in service in 1831.  Occasionally merchantmen or warships have been chartered or assigned for special duty as a temporary royal yacht, for example the steamship "Ophir" in 1901 and the battleship HMS "Vanguard" in 1947.  In 1997 HMY "Britannia" was decommissioned and not replaced.  Since 1998, following a successful national tender process, the Royal Yacht Britannia has been berthed permanently at the Port of Leith in Edinburgh.  There are currently no British royal yachts, although MV "Hebridean Princess" has been used by the Royal Family. Sir Edward Richard George Heath, (9 July 1916 – 17 July 2005), better known as Ted Heath, was a British politician who served as Prime Minister of the United Kingdom from 1970 to 1974 and Leader of the Conservative Party from 1965 to 1975.  He was a strong supporter of the European Communities (EC), and after winning the decisive vote in the House of Commons by 336 to 244, he led the negotiations that culminated in Britain's entry into the EC on 1 January 1973.  It was, says biographer John Campbell, "Heath's finest hour".  Although he planned to be an innovator as Prime Minister, his government foundered on economic difficulties, including high inflation and major strikes.  He became an embittered opponent of Margaret Thatcher, who supplanted him as party leader in 1975. The Swedish constitution of 1974 allows the Prime Minister of Sweden to appoint one of the Ministers in the cabinet as Deputy Prime Minister ("biträdande statsminister", also unofficially known as "vice statsminister", "Vice Prime Minister"), in case the Prime Minister for some reason is prevented from performing his or her duties.  However, if a Deputy Prime Minister has not been appointed, the Minister in the cabinet who has served the longest time (and if there are several with equal experience the one who is oldest) takes over as head of government.  Note that the person acting as Prime Minister does not do so on a permanent basis: if a Prime Minister dies, resigns or loses a vote of confidence in the Riksdag, the Speaker of the Riksdag will then confer with the parties of the Riksdag and propose a new Prime Minister, who must be tolerated by a majority of the Riksdag.  If the Prime Minister has resigned or lost a vote of confidence, he or she will remain the head of a government "ad interim" until the new Prime Minister assumes his or her office.  The only case where the governmental line of succession becomes relevant is when the Prime Minister dies (upon which the person next in the line of succession serves as the head of a government "ad interim") or when the Prime Minister is on leave or for any other reason incapable of serving, but still remains in office.  This might be compared to the Presidential line of succession in the United States, where the person next in line assumes the Presidency throughout the remainder of the term if the President dies, resigns or is impeached. Luis González Bravo y López de Arjona (Cádiz, Spain, 8 July 1811 – Biarritz, France, 1 September 1871) was a Spanish politician, diplomat, intellectual, speaker, author, philanthropist and journalist graduated from law school, who served twice as Prime Minister of Spain, or President of the Government of Spain (Spanish terminology for Prime Minister), from 1843 to 1844 and in 1868.  He held other important offices, such as once serving as Minister of State and Foreign Affairs, and twice as Minister of Home Affairs (see: List of Ministers of the Interior of Spain).  He was appointed Ambassador of Spain to the United Kingdom in Queen Victoria's rule, and Ambassador of Spain to Portugal.  He was the Spanish Prime Minister responsible for granting Chile its independence.  He was a member of the Moderate Party, and occupied three times the post of Spanish Congressman (United States House of Representatives equivalent) or Member of Parliament (House of Commons of the United Kingdom equivalent), for Cádiz, Jaén, and the Canary Islands.  He was provisional Minister of Justice for five days.  He was head of the Spanish civil troops "Milicia Nacional".  He was Knight of the Order of the Golden Fleece and Knight of the Order of Charles III (of King Charles III of Spain, Carlos III).  He founded four newspapers in Spain, and was the noted Spanish poet Gustavo Adolfo Bécquer's benefactor.
