A key BJP meeting chaired by its president Amit Shah today vowed to work to ensure the partys return to power in the Lok Sabha elections with a bigger victory than 2014 when it had won a majority on its own for the first time in its electoral history, sources said. A slogan of Ajey BJP (Invincible BJP) was adopted at the meeting of the partys national office bearers and also presidents of its state units. They pledged to work for the partys victory in assembly polls in five states and a decision was taken to give extra emphasis on the elections in Telangana, which is likely to go the polls with states like Rajasthan, Madhya Pradesh and Chhattisgarh. The BJP is confident of returning to power with more number of seats than it won in the 2014 Lok Sabha polls, a source said. Shah inaugurated the office-bearers meeting and it will be followed by a two-day meeting of the partys national executive.
