Scandals muddy Colombia election two weeks before voting

BOGOTA (Reuters) - Spying and bribery allegations have marred the run-up to Colombia's presidential election with top advisors for both candidates resigning in a bitter campaign that could sour voter support just over two weeks from the ballot.

Both President Juan Manuel Santos and his closest rival Oscar Ivan Zuluaga have been tarnished by mud-slinging between their camps, shifting attention in an election that was on track to be a referendum on the peace process with Marxist-led rebels.
