Voters in nine provinces headed to polling stations Sunday in the second round of Egypt's parliamentary election, balloting that so far has produced a surprisingly strong showing for candidates of the opposition Muslim Brotherhood. There are 1,706 candidates competing in 72 constituencies in the nine second-round provinces. As polling places opened, there were early complaints of irregularities. The NDP garnered 112 seats in the first round. All 454 places in the parliament are up for election in the three-stage process that concludes Dec. 1.
