Ukraine: Who will voters choose?

Voters in Ukraine go to the polls this weekend to elect a new parliament.

There are two main opposition parties, one led by the world heavyweight boxing champion, Vitali Klitchko, and the other by the imprisoned Yulia Tymoshenko, a longtime opponent of the country's president.

As Daniel Sandford reports from Ukraine, this election could have a major impact on the country's future and its relationship with the west.
