New Delhi, Jun 24 (IANS): Prime Minister Manmohan Singh leaves Friday for the G20 Summit in Toronto June 26-27 where he is also set to hold talks with his Canadian counterpart Stephen Harper and sign a bilateral nuclear cooperation pact on the lines India has with the US.

On the way to Canada, the prime minister's special aircraft, Air India One, will make an overnight technical halt in Frankfurt before proceeding onward to a packed itinerary at Toronto, officials said.

In a signal honour, Manmohan Singh will be the only visiting leader at the G20 Summit for whom Harper will host a dinner, soon after their bilateral talks, following the conclusion of the G20 Summit Sunday.

India and Canada are also expected to sign a host of other agreements during the visit, including those covering energy, culture and social security while also holding talks on a host of bilateral, regional and multilateral issues, officials said.

The G20 Summit will be no less important as the leaders of rich and emerging economies discuss how to come out of the global financial crises that has sent some countries to the verge of bankruptcy.

The prime minister returns to New Delhi late June 29, again after an overnight technical halt at Frankfurt.
