He said Governor Kaptan Singh Solanki would inaugurate the programme.
Pal said the former MLAs and MPs would be paid an honorarium of Rs 11,000 by Haryana Vidhan Sabha Secretariat for to and fro and making arrangement of boarding and lodging at their own level.

Haryana was carved out as a separate state on November 1, 1966 and it would be celebrating 50 years of its existence in the coming days.
