London is the costliest mission of India with an annual expenditure of over Rs 58 crore while the cheapest consulate is in Indonesia's Bali where expenses run into little over Rs 20 lakh.
This information was given by ministry of external affairs (MEA) in response to an RTI query posted by Mumbai-based activist Ajay Marathe, who was intrigued by the reports of expenses incurred on various embassies by India.
The total expenditure on maintaining 178 missions across the world was Rs 1497.58 crore in 2011-12 while it was Rs 1386.95 crore in 2010-11 and Rs 1374.48 crore in 2009-10.
Through his RTI petition, Marathe demanded from the MEA the expenses incurred on India's missions across the globe for the past five years.
In its response, MEA gave information for 2009-10, 2010-11 and 2011-12 for all its diplomatic missions.
The information revealed that expenditure incurred on high commission in London was Rs 58.67 crore for 2011-12.
Closely following in terms of expenses are missions in Jeddah in Saudi Arabia which incurred expense of Rs 45.63 crore in 2011-12, Kabul came next with Rs 39.09 crore and Paris spent Rs 36.38 crore during the year.
"I have come to know that some embassies were incurring massive expenses. In order to know the expenses of all the missions, I filed the RTI application," Marathe told PTI.
