It will be Chief Minister Arvind Kejriwal from tomorrow

Kejriwal will now face the immediate challenge of fulfilling a number of key promises like passage of Delhi Jan Lokpal Bill and cutting power tariff

Arvind Kejriwal will take charge of Delhi as its Chief Minister tomorrow in a meteoric rise to power after breaking away from anti-graft crusader Anna Hazare and launching Aam Aadmi or Common Man's Party a year ago with a pledge to clean up politics.

45-year-old Kejriwal, a Magsaysay award winner who quit Indian Revenue Services to fight graft and shot into limelight as an RTI activist and later with Jan Lokpal bill agitation, will take oath as Delhi's youngest Chief Minister along with six of his ministerial colleagues at a public function at the historic Ramlila Maidan which is expected to be attended by a large crowd.

After leading his party to a phenomenal success in the assembly polls, Kejriwal will now face the immediate challenge of fulfilling a number of key promises like passage of Delhi Jan Lokpal Bill, cutting power tariff by 50% and supplying 700 litres of free water to each household in the city.

He will be facing enormous public expectations as he had capitalised on the disillusionment of various sections of citizens -- be it autorickshaw driver, residents of slum clusters or middle class families -- with mainstream political parties.

Kejriwal is expected hold a meeting of his cabinet immediately after the oath taking ceremony and is likely to make certain announcements.

The AAP government, with outside support from the Congress, is likely to have little over two months' time to deliver on its immediate priorities as model code of conduct for the Lok Sabha polls is set to come into force in March.

His moves on the promise to probe allegations of corruption against the Sheila Dikshit dispensation will also be watched carefully as he led AAP to electoral victory pledging to root out corruption.

Kejriwal has already started the process of identifying "honest" officials in Delhi Government and indicated that they will be given important tasks.

Initially AAP had refused to take support from either Congress or BJP to form the government following which both the parties had accused it of shying away from the responsibility fearing that it would not be able to deliver on its promises.

On Monday, the party had staked claim to form the government after results of its 'referendum' overwhelmingly favoured it to take the reins of power.
