On the other side of the aisle, the JLP was founded by Sir Alexander Bustamante on July 8, 1943.
He was the undisputed leader of the party until 1974, when he was succeeded by Edward Seaga, who beat Wilton Hill in a bitter power struggle that threatened to divide the party.
The younger Manley was succeeded by PJ Patterson, who beat Portia Simpson Miller in 1992.
Simpson Miller would ascend to the leadership of the party in 2006 in a highly publicised, heated internal election, where she defeated Drs Peter Phillips, Karl Blythe and Omar Davies.
"It happens everywhere, I don't see why just because they're Gordonstoun boys it should be different." Gordonstoun School, rather warily, allowed me to visit the grounds and talk to a selected group of pupils.
Or so locals learnt from the newspapers, almost two weeks after the event."Police quiz Royal in gang brawl", the tabloids screamed, detailing a post-pub street fight between young men from Gordonstoun and Lossiemouth, complete with upper-crust cries of "Fight, you peasants! The facts of the dispute are now sub-judice; the local police have charged three men - one from Gordonstoun, two from Lossiemouth - and the Procurator-Fiscal of Moray (equivalent to the Crown Prosecution Service in England) is considering, in view of the police report, whether to proceed to court.
As Gordonstoun was eager to emphasise (while resolutely refusing to discuss its investigation into the fight), Peter Phillips, pupil, rugby star and grandson of the Queen, has been "eliminated from police inquiries".
Jamaica is known for fiercely contested general parliamentary elections every five years, dating back to 1944.
Of the 16 elections, the JLP has won on seven occasions – including the 1983 polls, which the People’s National Party (PNP) boycotted.
Besides the recent Shaw versus Holness match-up, the JLP has seen only one other challenge to an incumbent party leader: Mike Henry’s failed challenge to Seaga in 1978.
