AMMAN, Jordan — Members of the political arm of the opposition Muslim Brotherhood won seats in Jordan’s Parliament in a symbolic comeback, and women increased their numbers in the legislature, according to results of parliamentary elections released on Thursday.

Although most of the 130 seats in the lower house of Parliament were retained by pro-monarchy loyalists, the Islamic Action Front, the Brotherhood’s political arm, and other Islamists not affiliated with the Brotherhood won a total of 16 seats.

The Brotherhood had boycotted the last two elections to protest what it said were unfair practices in the electoral system that favored pro-government candidates. Jordan had stripped the Brotherhood of its official registration this year, but the Islamic Action Front remained registered and legal. The group decided to field candidates this time after the government adopted changes that encouraged the participation of political parties and opposition groups.

Jordan’s lower house of Parliament has limited political power or influence over the government’s policies. King Abdullah II appoints the prime minister, cabinet members and members of the upper house of Parliament.
