The BJP and its Bihar allies on Sunday sealed the seat-sharing arrangement for the Lok Sabha elections next year.

BJP president Amit Shah announced that his party and the Janata Dal(United) will contest 17 seats each, while the Lok Janshakti Party will get the remaining six in the state.

Shah made the announcement in New Delhi in the presence of Bihar chief minister Nitish Kumar and Lok Janshakti Party chief and Union minister Ram Vilas Paswan.

The LJP will also be given a Rajya Sabha berth and Paswan is likely to be its candidate.

While Shah made the announcement in Delhi, Prime Minister Narendra Modi hit out at the 'mahagatbandhan' for the 2019 Lok Sabha polls, calling it an 'unholy alliance' of various political parties for 'personal survival'.

People will see through the 'incoherent alliance of rich dynasties,' Modi said during his interaction with booth workers from Chennai Central, Chennai North, Madurai, Tiruchirappally and Tiruvallur constituencies in Tamil Nadu through video conference.

The Prime Minister said the key constituent of the mega alliance - the Telugu Desam Party - was formed against the 'high-handedness' of the Congress by N T Rama Rao but the party was now keen to join hands with the Congress.

'Today several leaders are talking about a grand alliance or Mahagathbandhan. This alliance is for personal survival, and is not ideology-based support. This alliance is for power, not for the people. This alliance for personal ambitions, not people's aspirations,' he said.
