Question: Ben Miles portrays a character in "The Crown" who had a romance with which member of the royal family?

Group Captain Peter Wooldridge Townsend, (22 November 1914 – 19 June 1995) was a Royal Air Force officer, flying ace, courtier and author.  Townsend also had a romance with Princess Margaret.  He was Equerry to King George VI from 1944 to 1952 and held the same position for Queen Elizabeth II from 1952 to 1953. <SEP> Benjamin Charles Miles (born 1 November 1966) is an English actor, best known for his starring role as Patrick Maitland in the British TV comedy "Coupling", from 2000 to 2004 and as Peter Townsend in the Netflix drama "The Crown" (2017). <SEP> The Order of Prince Danilo I of Montenegro (Montenegrin: Орден Књаза Данила I, Orden Knjaza Danila I) was an order of the Principality, and later Kingdom, of Montenegro.  It is currently granted as a dynastic honor by the undisputed head of the House of Petrović-Njegoš, Nicholas Petrović Njegoš II.  Although no longer a state order, recognition is indicated by the acceptance of the former President of Montenegro, Filip Vujanović.  More formal recognition by the Republic of Montenegro is implicit in the 2011 "Law on the Status of the Descendants of the Petrović Njegoš Dynasty", which recognizes the current crown prince as head of the Royal Family and specifically sanctions the use of the royal family's heraldic symbols.  The act also provides the Crown Prince housing and a pension and has been noted as conferring a sort of "quasi restoration" of the throne.  In a May 15th "Pobjeda" newspaper interview, Prince Nikola cited Article 3 of this law as the basis for his May 5th re-institution of the Order, which he emphasized was "historically an extremely valuable Montenegrin decoration."  He went on to explain that the order can be awarded to Montenegrin nationals and worthy foreigners on two general grounds: (1), for support and affirmation of Montenegrin independence and the royal tradition of the Petrovic Njegos dynasty, and (2) to those whose "scientific or social work contributed to the development of culture, art and science."  The Order has since been bestowed on a number of high dignitaries internationally.  In an April 17, 2016 visit to Rome, HRH Prince Nikola II Petrovic Njegoš met with Pope Francis and other high Vatican officials bestowing the dynastic honor on the Cambodian ambassador, His Highness Prince Sisowath Ravivaddhana Monipong, the Montenegrin ambassador to the Holy See Veselin Šuković, as well as the U.S. Ambassador to the Holy See Kenneth Francis Hackett, and the ambassador of Hungary HIRH Eduard von Habsburg-Lothringen, among several other Vatican officials and Italian nobles.  The official Representative of the Royal House and the order is H.E. Giuseppe Tedischi GCDO, who also has the Vatican charge "Addetto di Anticamera di Sua Santità," or Officer of Antechamber of His Holiness. <SEP> In Canada, a number of sites and structures are named for royal individuals, whether a member of the past French Royal Family, British Royal Family, or present Canadian Royal Family thus reflecting the country's status as a constitutional monarchy under the Canadian Crown.
