1) Lenin Moreno (current government candidate) wins in this first round by getting at least 40% and being at least 10% ahead of the second place candidate.2) Moreno is joined by second placed candidate Guillermo Lasso in a second round run-off, that would happen on April 2nd if necessary.
UPDATE: At just before 8:30pm local time we have just been given the results of 51% of counted votes, official numbers and we're firming up towards the final score. The need to know is:
Lenin Moreno 38.26%The rest is noise. It's looking like a second round run-off.
Guillermo Lasso: 29.86%
UPDATE 2: Now 72.3% counted and the percentages remain very similar, Moreno 38.66% and Lasso 28.92%. This is now very likely going to the run-off.
