Prime Minister Narendra Modi asserted on Wednesday that results of the Bihar assembly polls and bypolls across states have proved that "development" will be the only basis for politics in the 21st century and credited women for powering the BJP's political fortunes as its "silent voters".

Addressing BJP workers at a thanksgiving programme here following the electoral victory, PM Modi also attributed the NDA's win in Bihar to its mantra of "sabka saath, sabka vikas, sabka vishwas" and also launched a veiled attack on the West Bengal's ruling Trinamool Congress, saying those who cannot challenge the party democratically have resorted to "murdering" its workers to realise their goals.
