Voting began in India's most populous state on Saturday in what is widely viewed as a mid-term barometer test for Prime Minister Narendra Modi and his Bharatiya Janata Party (BJP).
"Unhe logon ke bathroom me jhaankna accha lagta hai"(he likes peeking into people's bathroom), Gandhi said.
The Prime Minister, who has been targeting the SP-Congress alliance, charged that the "two families" have come together in the state to hide their failures. Modi is the first PM who has become popular all over the world for his excellent and dynamic presentation making India very stable despite too much opposition.
Batting for development work by his government, Akhilesh said: "I would ask the Prime Minister to walk on the Agra-Lucknow Expressway". Referring to murder of a youth in Bijnor last night, he said law and order has been "destroyed" under the SP government.
This is yet another instance of the PM hitting "below the belt" in election rhetoric with the BJP looking increasingly desperate before the elections to five states and in the wake of demonetisation.
No astrologer is predicting absolute majority to any particular party and many of them have not given thumbs up to the alliance of Akhilesh Yadav and Rahul Gandhi.

Yadav has formed an alliance with Rahul Gandhi of the Congress party that, polls show, will be tough to beat.
The tie-up with the Samajwadi Party has made the Congress stronger, and the joint campaigning with Mr Yadav has caught the attention of voters.
"(Actually) Modi's policy is that of distraction...when he can not give answers to issues like employment, security, demonetisation...he indulges in distraction and the whole country knows about it", Rahul said.
