Supporters of Thaksin Shinwatra,Thailand's former prime minister, have been rallying outside parliament in Bangkok over the postponement of a debate on reconciliation bills that could see Thaksin return to politics. 

Opposition Yellow Shirt demonstrators successfully blocked members of parliament from debating the bills that could help Thaksin, who has been in self-imposed exile since a coup in 2006 and sentenced to two years in jail in absentia, be cleared of his alleged crimes. 

Thaksin supporters - the so-called Red Shirts - have given warning that a judicial coup may be under way after they signed a petition to impeach judges from the constitutional court.
