Taking a swipe at the Centre, Shiv Sena MP Sanjay Raut on Monday said a notice issued by the Enforcement Directorate (ED) is not a "death warrant" but a "love letter" for political workers, a day after Sena leader and Maharashtra minister Anil Parab was asked to appear before the anti-money laundering agency.

"Frequency of such love letters has increased after unsuccessful attempts to breach the wall of the Maha Vikas Aghadi (MVA) which is strong and impregnable," he told reporters.
