Mexico's ruling party has lost ground in key midterm elections.
Election officials say President Vicente Fox's National Action Party lost 49 seats in the July 6 balloting - giving it 153 seats in the lower house of the legislature.
The rival Institutional Revolutionary Party, or PRI, made slight gains, winning 224 seats.
Last week, President Fox urged his government and lawmakers to work together to achieve consensus after preliminary results showed his party's loss.
Mr. Fox won the presidency in July 2000, ending more than seven decades of consecutive rule by the PRI.
