New Delhi: The Election Commission today cautioned RJD chief Lalu Prasad Yadav for his reported casteist remarks which it said violated model code and asked him to be 'more careful' in public utterances during election campaigns in future.

"...the Commission has considered your reply carefully and has observed that you have not denied having made the impugned statements...the explanations furnished by you in support of justifying those statements have not been found convincing by the Commission," the EC said in its order.
