The Congress on Friday dismissed as "laughable" the complaint seeking disqualification of its chief Sonia Gandhi from the Lok Sabha for receiving a Belgian honour and said it will give a "strong and fitting reply" to the Election Commission notice to her.

"The complaint is baseless and motivated. To suggest that receiving of a foreign citation or decoration is office of profit or foreign allegiance is laughable," said party spokesperson Abhishek Singhvi.

He said every adjudicating authority "must act as a filter at the threshold, separating the grain from the chaff, fake and frivolous from the relevant," he said.

Singhvi said every complaint need not necessarily lead to a notice but the party "will give a strong and befitting reply".
