Tesco posted 6 per cent fall in group trading profit to 3.3 billion pounds in the year to February 22.
In the UK, profits fell 3.6 per cent to 2.2 billion pounds and sales dropped 1.4 per cent.
"Our results today reflect the challenges we face in a trading environment which is changing more rapidly than ever before. We are determined to lead the industry in this period of change," said Tesco chief executive Philip Clarke.
Tesco had finalised a deal to become the first foreign supermarket to enter India's 330-billion pound multi-brand retail sector last month.

Tesco also revealed a one-off charge of 801 million pound mainly relating to a write-down of assets in Europe, as well as a 540 million pound impairment relating to its Chinese business.
"During the year, we have maintained our focus on cash and capital discipline. We have significantly reduced our new investment in Europe, focusing the majority of our overseas capital on targeted, high-returning investments in Korea, Malaysia and Thailand," Clarke said.
