(Reuters) - A week of protests and minor scuffles between pro- and anti-government supporters in Bangkok has raised fears that the army may storm back into Thai politics after nearly three years of instability and a coup.
Here are some milestones since the protests that sparked the putsch in September 2006:

* September 19: Military stages coup ten days after Thaksin heads overseas on tour. He goes into exile in London.
* October 1: Former army commander-in-chief Surayud Chulanont sworn in as interim prime minister. Thaksin steps down as Thai Rak Thai (Thais Love Thais) party leader two days later.
* February 21, 2007: Somkid Jatusripitak, a former finance minister and architect of Thaksin’s pro-business policies, quits as economic adviser to interim government after six days.
