P Chidambaram – Former Union Finance Minister:

In an interview to TIMES NOW recently, the FM sneered at UPA II for high inflation and retrospective tax

Under UPA II, the worst year of inflation was 2010-11.
Average WPI reached 9.6 per cent but declined year after year to 6 per cent in 2013-14

The retrospective tax was imposed in Budget 2012-13

There was a strange reluctance on the part of FM to name the finance minister who was in office during 2011-12 and who presented the Budget for 2012-13.

I wonder why?
