Thai Prime Minister Yingluck Shinawatra has celebrated her unlikely first year in power after winning a landslide victory last election at the helm of her brother's political party - one that had been ousted in a coup five years ago.

Having led the Pheu Thai party into a big election win with no previous political experience, Yingluck, a former businesswoman, has cause to celebrate.

But while Yingluck's administration has a strong mandate, opponents have warned that by moving too fast to push through reconciliation laws and rewrite the constitution, she risks making her hard-fought changes only temporary.
