KATHMANDU: CPN-UML Chairman KP Sharma Oli on Friday accused the Madhesi parties of confusing people by raising 'unnecessary agendas.' 'Instead of holding elections at three tiers to take the nation out of transition,' he said, addressing a function in Kathmandu today, 'The Madhes-centric parties have been raising unnecessary issues and confusing people.' Oli, however, said his party would not allow such activities get success and let the nation move backward. 'Now, we should not commit mistakes as in the past,' the former Prime Minister added, 'We should accelerate the pace to build the nation.'
