Thailand's election commission has certified all but a handful of the winners in July 3 elections, clearing the way for parliament to open its session on Monday.

The chamber is expected to select Yingluck Shinawatra, candidate of the winning Phue Thai party, as Thailand's first female prime minister before the end of the week.

The election commission certified 94 candidates late Wednesday, leaving only four of the 500 winners still unable to take their seats. Under Thai election law, at least 95 percent of the candidates must be certified before the parliament can convene.

Among the candidates who were not certified is Jatuporn Promphan, a leader of last year's Red Shirt protests who is facing terrorism charges.

Ms. Yingluck's party won an outright majority in the election and formed a coalition with smaller parties that gives it about three-fifths of the 500 seats.

She is the younger sister of Thaksin Shinawatra, a popular former prime minister who was ousted in a military coup in 2006. Mr. Thaksin was later convicted in absentia on corruption charges and is living in self-imposed exile in Dubai.
