Congress President Sonia Gandhi will undertake a one-day visit to Karnataka tomorrow, her second this year, to galvanise partymen for next year's assembly election.

During her visit to the coastal town of Mangalore, she would address prominent leaders of Udupi and Dakshina Kannada district and party workers, Congress sources said.
Later, she would launch the 'Kudroli Gokarnatha Temple Centenary celebrations' and Mangalore Dasara festivities, they said.

In April, she had participated in the Guruvandana programme and birthday celebrations of centenarian Sri Shivakumara Swamiji, the pontiff of Siddaganga mutt in Tumkur.

Her visit to this coastal district assumes significance as Congress is trying to re-establish its popularity in this region which has now become a BJP stronghold.

KPCC President G Parameshwara and Opposition leader in the assembly Siddaramaiah will be brief Sonia Gandhi on the present political scene in Karnataka, Cauvery water-sharing issue and also the internal bickerings in ruling BJP, they said.
