The Army is thinking of taking up the issue with the Election Commission through proper channel, Army sources said here.
They, however, said a final decision in this regard would be taken at a higher level in the Army Headquarters as it involves two major national political parties.
The Congress had yesterday sought derecognition of BJP in the wake of "provocative" advertisement issued by it in poll-bound Madhya Pradesh, where the national flag and the photo of the Army Chief were "misused".
The complaint was against Madhya Pradesh Chief Minister Shivraj Singh Chouhan and state BJP chief Narendra Singh Tomar. He alleged that the BJP was seeking to drag the Army chief in politics by using his photo.
