New Delhi: Delhi Chief Minister Arvind Kejriwal on Thursday congratulated Trinamool Congress supremo Mamata Banerjee on her victory in the West Bengal Assembly polls.

Banerjee has invited Kejriwal for her swearing-in ceremony scheduled to be held on 27 May.

"The Delhi Chief Minister called up the TMC supremo and congratulated her on her party's victory in the Assembly polls," said a senior Delhi government official.

"Congratulations Didi for stupendous victory..." Kejriwal tweeted. Both leaders have good political relations.

In April last year, Kejriwal had also congratulated Mamata on her party's victory in municipal corporations in West Bengal.

When the AAP government had organised a conclave of Chief Ministers in the national capital in September last year, the TMC leader had shared the stage with Kejriwal and assailed Lt Governor of Delhi Najeeb Jung for frequently annulling Delhi government's orders.

They together had pitched for the supremacy of elected governments, demanding complete de-centralisation.
