Kolkata, July 30  West Bengal Chief Minister Mamata Banerjee on Saturday claimed the state's gross domestic product has more than doubled since 2010.

"You will be happy to know that the Gross Domestic Product (GDP) of West Bengal has more than doubled from nearly Rs 4.61 lakh crore in 2010-11 to Rs 9.20 lakh crore in 2015-16," Banerjee said on Facebook.

The Trinamool Congress supremo ascribed the "quantum jump" partly to "massive increase in plan expenditure and partly due to huge creation of permanent assets in the state through increased capital expenditure".

"Just to share with you, plan expenditure in the state has increased by nearly four times from Rs 14,615 crore in 2010-11 to Rs 54,069 crore in 2015-16 and capital expenditure has increased by nearly seven times from Rs 2,225 crore in 2010-11 to Rs 15,946 crore in 2015-16," she said.
