With his health improving fast, Prime Minister Manmohan Singh is expected to attend the G-20 Summit in London on April 2, a visit that will provide an opportunity for his first meeting with US President Barack Obama.

"The prime minister intends to attend the G-20 and preparations are being made in this regard," an official said in New Delhi on Tuesday.

However, a confirmation about the visit is awaited and it would depend on Singh's health condition and a clearance from doctors, the official said.

Meanwhile, a team of Indian officials is in London for preparations for the prime minister's visit.

Singh underwent a bypass surgery on January 24 and has since been recovering fast. He has started attending to some work and a few official functions.

During his expected visit, Singh will have bilateral meetings with some world leaders. This will include a meeting with Obama, their first since the new US President took over on January 20.
