Condoling the death, Chief Minister Pinarayi Vijayan said that she worked tirelessly for the rights of women and her legal fight which she won will always be remembered.

Two-time former Chief Minister Oommen Chandy, who also hails from Kottayam, said she will always be remembered for being instrumental in Christian women getting a share in their family property besides the school that she set up.
