Tirupati: Andhra Pradesh Chief Minister and TDP chief N Chandrababu Naidu Saturday mounted a strong attack on the YSR Congress alleging it was colluding with the BJP-led NDA and the Telangana Rashtra Samithi against his government.

Launching his campaign for the April 11 Lok Sabha and State assembly polls after offering prayers at the Lord Venkateswara shrine near here, Naidu said the people would give a fitting reply to these parties in the elections.
