Here are some examples:
* "The politician was accused of being in bed with the oil industry." This suggests the politician is working closely with the oil industry in a way that may be considered unethical, perhaps by accepting bribes or favors.
* "The company was in bed with the government to get the contract." This implies the company used its relationship with the government for an unfair advantage.
* "The two rival companies were in bed with each other to drive up prices." This suggests the companies were secretly working together to harm consumers.
The idiom's origin likely comes from the idea of two people sharing a bed, implying intimacy and cooperation. However, the idiom is typically used in a negative context, highlighting a close relationship that is considered morally questionable or corrupt.
