The Irrigation and Flood Control portfolio has been given to PWD Minister Satyendar Jain from senior AAP minister Gopal Rai, sources said on Tuesday.
The change in Rai's portfolio has been made to ensure coordination between the I&FC and the Delhi State Industrial Development Corporation (DSIDC), they said.
The two bodies are mandated to carry out development works in unauthorised colonies.
Rai has the portfolios of labour, employment, general administration and development departments.
In June 2016, Rai was also relieved of the charge of the transport department and it was then given to Jain. Later, the charge of the transport department was given AAP MLA Kailash Gahlot.
