Sonia Gandhi attends first public event after surgery
The leader of India's governing Congress party, Sonia Gandhi, has made her first public appearance after returning from the US following surgery for an undisclosed medical condition.
Mrs Gandhi attended a prayer meeting to mark the birthday of Mahatma Gandhi, India's revered independence hero.
Mrs Gandhi holds no government post but holds enormous political power.
The 64-year-old Italian-born politician is seen as a key decision-maker in the government.
Correspondents say the Indian government faced serious problems during her month-long absence.
Prime Minister Manmohan Singh's government was severely criticised for mishandling anti-corruption protests in August by social activist Anna Hazare.
Many commentators said that if Mrs Gandhi had been in Delhi, she would have handled the situation better.Cancer rumours
The party has consistently refused to comment on the nature of the illness or where she went for surgery.
But media reports have suggested she was treated at a specialist cancer hospital in New York.
Mrs Gandhi is the widow of former Prime Minister Rajiv Gandhi. She nominated Manmohan Singh to the prime minister's post in 2004 but is frequently portrayed as being more powerful than him.
She is at the head of the Nehru-Gandhi dynasty, which has ruled India for most of the time since independence in 1947.
Her son and MP Rahul Gandhi is tipped as a future prime minister.
