Newsflash! Online encyclopedia Wikipedia is shortly to be sued (Singapore Review via Singabloodypore):

http://en.wikipedia.org/wiki/Nepotism
"Nepotism
is a common accusation in politics when the relative of a powerful
figure ascends to similar power seemingly without appropriate
qualifications. For example, in America, politically powerful families
such as the Kennedy family and Bush family in American politics are
sometimes accused of nepotism by critics…
Families elsewhere have also dominated politics of their
homeland, such as … Minister Mentor Lee Kuan Yew (first Prime Minister of
Singapore) and his son, Lee Hsien Loong, who recently succeeded Goh
Chok Tong as Prime Minister of Singapore."

Family dictatorship
"A
family dictatorship is a form of dictatorship that operates much like
an absolute monarchy, yet occurs in a nominally republican state and is
not part of its laws. When the dictator of a family dictatorship dies,
one of his relatives (usually his son) becomes the new ruler of the
country. This transition often occurs after years of "grooming" the
dictator’s successor as heir apparent."
