Former prime minister Yulia Tymoshenko (left) has received support from Ukranian President Yushchenko

Final official results from September 30 parliamentary elections were released Monday, confirming that Yushchenko's party and that of former prime minister Yulia Tymoshenko won a majority in parliament, giving them the right to form a cabinet.

Together, the parties won 228 seats in the 450-member legislature, Central Election Commission spokesman Konstantin Khivrenko said -- two clear of a majority. The rival party led by Prime Minister Viktor Yanukovych won more votes than any other, but it was only enough for 175 seats.

After holding talks with the president, Tymoshenko and the leaders of the pro-Yushchenko party signed an agreement that gives Tymoshenko's party the right to name the prime minister -- virtually assuring she would get the post -- and allows Yushchenko's party to name the parliament speaker.
