Vaigai Puyal was known to
be among the people closest
to the Puratchi Kalaignar.
Vijayakanth is known to
have helped Vadivelu a lot
during the initial phase
of his career. How or when
things went wrong between
them is not well known,
but there are hints that
the reasons might be political.
Seeing the extent to which
their disputes have gone
(even up to court), there
seems to be little chances
of a patch up. Vadivelu
has even said that he would
pitch against Vijayakanth
in the next assembly elections.
