Tunisia held up as the one success story of the #ArabSpring uprisings a decade ago. Now its new democracy is under threat after its president, Kais Saied, suspended parliament and dismissed the prime minister.

The President's supporters have celebrated the move - but his critics call it a political coup. And it's led to clashes in the capital Tunis. Simon McGregor-Wood reports.
