Colombia is going to the polls on Sunday to elect a new president.

Alvaro Uribe, the incumbent, was prevented from changing the constitution to run for a third term. However, Juan Manuel Santos, of Uribe's party and his former defence minister, is running and viewed as the candidate that will continue his former boss' policies.

However, Santos has lost ground in the polls, now being virtually level with Antanas Mockus, of the Green Party.

Mockus is predicted to win a second round run off against Santos.

Unemployment, healthcare and poverty are the most important issues for voters. Al Jazeera spoke to some of them.
