New Delhi: Congress leader Rahul Gandhi used the word "alethophobia" on Thursday to take a swipe at the government over its reported decision to amend pension rules.

"Alethophobia -- the fear of truth," he wrote on Twitter, citing a news report quoting former intelligence and security officials that the new pension rules are a gag order.

According to the report, the amendment to Rule 8 means that pension can be withheld or withdrawn if the pensioner disobeys the rules and retired officials have to sign an undertaking to this effect.
