Senior Congress leader Shashi Tharoor today explained the party's insistence on having the Gandhi family in the leadership role, saying the party has felt for "sometime" that they have been "effective". He also underscored that with several state elections due to come up this year, there is no time for the Congress to "sit and mope". Rahul Gandhi, Mr Tharoor said, has impressed everyone by his willingness to take responsibilities. That he is serious on the resignation, shows "he is taking it on the chin and taking it personally," he added.
