I am sure the major credit for all these achievements should go to the BJP Govt in the State.
Communally also the State was much more peaceful when compared to ohter States. Because Mr.Modi had crushed/disabled all those who have been taking law into their hands during riots. He has been following non-appeasement policy all these years. That could be another reason for the communal harmony in Gujrat.
This has envied Congress and its allies, who have been crying from the roof top, that BJP and Modi are communal, whereas the fact is that Congress and its allies are highly communal, pseudo seculars, and following appeasement policies for the sake of votes.
