While Arvinder Singh Lovely and Mangat Ram Singhal are the new faces, AK Walia, Haroon Yusuf, Raj Kumar Chauhan and Yogendra Shastri have been reinducted into the ministry.
Lieutenant governor Vijai Kapoor administered the oath of office and secrecy to 65-year-old Ms Dikshit and the six ministers at an impressive function at Raj Niwas here.
Riding on the twin-plank of governance and development, Ms Dikshit became the first chief minister to get a second successive term to rule Delhi after it got the status of National Capital Territory in 1998.

The Congress, which first wrested power in Delhi in 1998 ousting BJP, won the December 1 Assembly polls with two-third majority for the second time.
Considered close to the Gandhi family that helped her keep her opponents within the party at bay, Ms Dikshit single-handedly walked away with credit for an impressive show at the hustings.
While lovely fills the Sikh vacancy caused by former finance minister MS Saathis defeat in the polls, Mr Singhal represents the influential trading community.
Immediately after taking oath, the Cabinet met and decided to convene a four-day session of the new Assembly from Thursday to enable the new members to take oath and elect the next speaker. The new MLAs will take oath on Thursday.
