"Business is quite comfortable with Dr Manmohan Singh and UPA finance ministers but there are sections of businesses which are extremely comfortable with Mr Narendra Modi because his brand of capitalism is crony capitalism," he said.
On the contentious issue of the gas price hike, the minister said there was no obligation on the Oil Ministry to seek the Election Commission's nod on a cabinet decision and added it was done only as matter of abundant caution.
