"You are trying to run with the hare and hunt with the hounds," he told Sukhbir and his father Chief Minister Parkash Singh Badal, referring to their "double standards" of "saying something and doing something else".
If they are seriously feeling "aggrieved why are they not withdrawing Harsimrat Kaur Badal from the Union Cabinet", he asked, adding, "This is a classic case of having and eating the cake at the same time."
In a statement, Amarinder claimed that in view of the strong possibility of the Supreme Court of India ruling against Punjab on the Sutlej Yamuna Link (SYL) canal issue, and the NDA government's clear stand in favour of Haryana, the Badals were now trying to prepare ground and make some excuse for exit.
"The father-son duo is preparing the ground to shirk off all responsibility and pass it on to the Centre despite their party still being part of the government there," he observed.

"Show me a single word you wrote to the Prime Minister on the issue," he challenged the Badals.
Amarinder alleged despite Congress' clear and unambiguous stand and support to the government on the SYL issue, Badal is "deliberately doing flip-flop to make some political capital out of it".
"But let me tell you, your bluff has already been called and you stand exposed among people that you stayed as a mute spectator while the NDA government at the Centre supported Haryana on SYL," he claimed.
"Badal is capable of doing anything for his own survival even if it means putting peace and harmony in Punjab at stake," he alleged.
