She was addressing a gathering of Youth Congress at the Talkatora stadium in New Delhi.
Dikshit asked youth Congress workers to work with the objective of strengthening the party, thereby paving way for Gandhi to become the Prime Minister.
"We must dedicate ourselves to the party. We will have to ensure that Rahul Gandhi occupies the top post and lead the country," she said.
Appealing to party workers to work hard for the upcoming Delhi assembly polls, she exuded confidence of fourth straight victory.
Dikshit took a dig at opposition parties and said they do not have an agenda for development of the city.
Congress general secretary Shakeel Ahmed, Delhi Pradesh Congress Committee President JP Agarwal, Youth Congress president Rajeev Satav and MP Sandeep Dikshit were also present on the occasion.
