A court's suspension of Thai Prime Minister Paetongtarn Shinawatra has raised questions about whether her family's political comeback will end with another downfall.

It was a Thai court decision last year that swept Paetongtarn Shinawatra into the prime minister's office and now, once again, the fate of the 38-year-old novice politician lies in the hands of the judiciary.

The 38-year-old has two weeks to respond to the probe. She has apologised and said her approach was a negotiating tactic.
