evidence: The Prime Minister’s office on Friday disclosed Manmohan Singh’s foreign trip expenses since he became Prime Minister nine years ago as Rs 620 crores. This is to create transparency under section 4 of the RTI Act, 2005. The website lists 67 trips of which they have received bills for 64. While Singh’s first trip was to Bangkok in July 2004, his last listed trip was to Germany in April 2013. [...] The information was revealed after a huge controversy erupted in March 2012 over the fact that Pratibha Patil’s foreign trips cost the public exchequer a whopping Rs 205 crore, surpassing the record of all her predecessors.
