He said that the party was fully with the people of Kerala at this hour of crisis. The situation in Kozhikode, Malappuram, Palakkad and Wayanad inched towards comparative normalcy as rains slowed and the water level receded, with many living in crowded relief camps awaiting to return home.

The deadliest deluge in close to a century has claimed 210 lives since August 8 and almost 400 since May 29 when the south west monsoon set in over Kerala.

Heavy rain, landslides and the flood have claimed nearly 40 lives so far.
However, the India Meteorological Department has indicated that relief may be around the corner.
Kerala, which usually receives high rainfall, has seen more than 250 percent more rain than normal between August 8 and August 15.
But roads and 134 bridges have been damaged, cutting off remote areas in the hilly districts of Kerala which are worst affected.
High-range Idukki recorded the highest excess rainfall (92 per cent above normal) followed by Palakkad (72 per cent above normal).
The southern state is struggling to cope with floods caused by the unusually heavy monsoon rains. The authorities are carrying out rescue operations on a war footing.
Tamil Nadu Chief Minister Edappadi Palaniswami announced on Sunday that all AIADMK lawmakers would donate their monthly salary for relief and rescue work to the flood-battered state of Kerala.
More than 1,000 people have died in flooding in seven Indian states since the start of the monsoon season, including more than 350 in Kerala.
While more than 300,000 people have taken shelter in relief camps, particular fears have been raised for Chengannur, about 120km north of the state capital Thiruvananthapuram, which has been cut off for four days.
