Many believe the political strife has worn the King out, especially the world record 541 days that he was royal mediator between squabbling communities when Belgium was without a government following elections in 2010 where Flemish republican separatists became the country's largest party.
As well as playing the difficult role of national mediator, Albert has faced a number of royal scandals that have damaged the standing of the monarchy, including a current court case brought by Delphine Boel, 45, an artist, alleging that she is his illegitimate daughter.
The abdication will give Prince Philippe, who is not popular in Flanders, time to make his mark as king before difficult national elections next year. "The abdication will enable the future king to meet political leaders ahead of the elections," said Caroline Van Wynsberghe, a political scientist at the Brussels ULB university. "Everyone fears a repeat of the 2010-2011 crisis."
Prince Philippe
The 53-year-old Prince is an experienced fighter pilot and parachutist with degrees from Trinity College, Oxford, and Stanford University. He is married to Belgian-born Princess Mathilde with three children. His daughter Princess Elizabeth, 11, will be the next in line to the throne.
