South Korean MPs have set a new world record for the longest combined filibuster in history after speaking for 192 hours.

Politicians from the opposition Minjoo Party took turns speaking at the podium for five hours at a time, outlining their concerns that a government-sponsored anti-terrorism bill would limit personal freedoms.

Although they were unable to hold up the vote any longer, and the bill was passed on Wednesday, their filibustering effort is an old political tactic - as the BBC's Michael Hirst explains.
