The highpoint of 66-year-old Gandhi's political career came in May 2004 when she successfully led the Congress to power at the Centre via the coalition route.
After securing power, she declined prime ministership and instead nominated economist-turned-politician Manmohan Singh to the top executive post in the country.
She took over the reins of the organisation in March 1998 in the wake of the party's dismal showing in the 1998 Lok Sabha polls that saw the exit of the late Sitaram Kesri from the post.
She has so far been unanimously elected to the post barring once when Jitendra Prasada, a senior leader from Uttar Pradesh, had thrown his hat in the ring but failed miserably in the polls in 2000.
Gandhi is currently in the fourth term of the Presidentship in which she was elected unopposed in 2010. Her term expires in 2015 in the wake of the changes in the party constitution that now mandates organisational polls after five years instead of three years earlier.
