The country needs to have a new president in place by November 11 when the current President's term ends.
The EC had earlier scheduled the run-off for November 16, but brought it forward to tomorrow to avoid a constitutional crisis.
However, EC member Ali Mohamed Manik told news portal Haveeru that JP is yet to sign any lists for the run-off, while PPM has stopped signing them today.
“If there has to be a second round, it is to be held tomorrow. However, we are facing some obstacles,” said Thowfeek.
