The ruling AIADMK on Friday allotted 20 seats to its ally BJP for the upcoming Tamil Nadu assembly election. This is three less than the 23 seats allotted to the other regional ally, PMK. The names of the seats that would go to the BJP are yet to be released. The national party has also been allotted the Kanyakumari Lok Sabha seat that would go for bypolls following the death of Congress MP Vasanthakumar.
