The SAD-BJP alliance is "everlasting" and both the parties should not be seen as different from each other, he told reporters here.
"The tried and tested alliance between the two parties is a unique phenomenon of the Indian democratic system. It has passed every litmus test in the last few decades," the 5-time Chief Minister said.
It is a sheer wastage of time to raise any suspicion regarding the relationship between both the partners, he said.
"Our alliance is very strong," the 86-year-old Chief Minister said. Badal was responding to questions on seat-sharing between the BJP and its ally Shiv Sena for coming Maharashtra assembly polls.
The seat-sharing in Maharashtra is the personal matter of both the parties and it should not be linked with that of the SAD-BJP in Punjab, he said. "The relations between the SAD and the BJP are very cordial.
They have been time and again cemented with mutual affection and understanding," Badal said. "The SAD-BJP government has put Punjab on high growth trajectory," he said.
Earlier, Badal paid floral tributes to Shiekh Baba Farid and said his life and philosophy is very much relevant in todays materialistic society.
