Tesco is expected to reveal full-year profits of £2.2bn tomorrow.

Analysts are predicting that the UK's number one supermarket group will unveil group sales of approximately £38bn and pre-tax profit of £2.16bn-£2.2bn.

They have also predicted that Tesco will record like-for-like sales growth of 5.7% excluding petrol.

Reports also suggest that the retailer will reveal plans to overhaul its property portfolio in a move that could see up to £1bn returned to shareholders.

Meanwhile, Tesco is also expected to announce plans to spend £100m on researching more environmentally friendly ways to power its stores.

Lucy Neville-Rolfe, Tesco's corporate and legal affairs director, said: “We will use this fund to pioneer a number of innovative projects including gasification of waste to power our distribution centres.”

She added: “If successful these investments will make a real difference to climate change.”
