Speaking at the Abhinandan Samaroh in the Talkatora Stadium, Gadkari said, "In one of the luxury hotel of Delhi, a big businessman brokered a deal between the AAP and the Congress. In that meeting, whatever their leaders ate and talked about was revealed by a person to me. The mediator told me that their single point agenda was to stop the BJP from coming to power in Delhi."
Gadkari's comments came hours after Kejriwal was sworn-in as the seventh chief minister of Delhi on Saturday by Lt. Governor Najeeb Jung.
Gadkari said the government in Delhi is not of the AAP but it belongs to the Congress.
He alleged that the AAP and the Congress are both the same side of a coin and it is the mission of the BJP to fight against their alliance.
"We will fight with all of our might and will win all the seven Lok Sabha seats of Delhi," he said.
"The man who had vowed on his son that his party will not extend or take support from any party, today became the Chief Minister of Delhi from the support the Congress. And it is a bad luck of the Congress, that there was no member of their party in the swearing-in ceremony of Kejriwal, the person they support. It is an example of Congress's tragedy and state," he added.
Along with Kejriwal, six other AAP MLAs were also administered oath of office and secrecy.
The swearing-in ceremony was witnessed by tens of thousands of people, a majority of them AAP supporters, who cheered boisterously as the oath was taken. They also waved coloured balloons and the tricolor.
Earlier, Kejriwal and AAP MLAs traveled to the formal swearing-in ceremony at Delhi's Ram Lila Ground on the Delhi Metro.
Kejriwal became Delhi's youngest chief minister today at the age of 45.
After the oath-taking ceremony, Kejriwal and AAP legislators will hold their first cabinet meeting. They are expected to work on Sunday as well.
He has been asked to prove his majority in the state assembly by January 3.
His first big challenge is to grapple with a 10 per cent hike in CNG prices, announced on Thursday.
Auto drivers in the city, who form a huge section of his supporters, have threatened a strike.
Kejriwal said yesterday he would see if the hike could be reversed. If that's not feasible, he said, auto fares are likely to increase.
The former Indian Revenue Service official has promised to disassemble Delhi's VIP culture. Neither he, nor other AAP lawmakers will use the flashing red lights that give politicians' cars the right of way on roads. They have also refused large government bungalows and say they want small flats as their official accommodation.
It was those principles and a declaration of war against corruption that gave AAP 28 seats and a second place finish in the December 4 elections.
The BJP and allies got the most -- 32 -- while the Congress finished third with just eight seats.
