New Delhi: A mega rehearsal has been planned for Wednesday in the central hall of the Parliament ahead of the historic launch of the goods and services tax (GST) on the midnight of 30 June.

The rehearsal, scheduled to be held at 10pm, may be supervised by either parliamentary affairs minister Ananth Kumar, his deputies Mukhtar Abbas Naqvi and S.S. Ahluwalia, or secretary Rajiv Yadav, officials said on Tuesday.

Officers concerned from various departments including those from the finance ministry will be part of the rehearsal event, they said.
