BJP said it was committed to bring the country's economy back on track, usher in speedy growth and tame inflation.
"This is just the beginning of the good days... It is the result of the leadership given by Prime Minister Narendra Modi and the new government's efforts in bringing the economy back on track of fast growth," BJP secretary Shrikant Sharma said.
He said the BJP-led government inherited an economy which was in bad shape and it will take some time to bring it back on the track of speedy growth and development.
Sharma said the growth rate recorded in this quarter after the BJP government came to power was the highest in the past two-and-a-half years and was the result of initiatives announced in this year's Union Budget.
He said the initiatives gave a boost to manufacturing, mining and services sectors, resulting in the economy bouncing back to the 5.7 per cent growth rate.
"Given our past record of keeping the country's economy in good shape, the party is committed to the nation's fast growth and keeping the economy robust," he said.
Hitting out at his political opponents, he said the growth in economy has silenced all those making fun of the "achhe din" (good days) remarks made by Prime Minister Modi.
Improved performance of mining, manufacturing and services sector pushed India's economic growth rate to two-and-half year high of 5.7 per cent in the April-June quarter, a development which the Finance Ministry expects to continue for rest of the fiscal.
