Putin became PM in 1999, did 2 terms as President 2000-08, was PM 2008-11 and is now serving a 6 year term as President, which will give him 18 years in the 2 top positions in Russia.

Could similar situations arise in other countries, accounting for different political systems?

In Australia I'm thinking perhaps a PM moving into the Senate after an election loss and then winning back the PM at the next election.
