Analysts are expecting Tesco to report like-for-like sales growth of between 4.5% and 6% when it updates the City on Christmas trading tomorrow (Tuesday).

Much of the growth is expected to come from non-food, with analysts especially keen to find out how its non-food venture Tesco Direct, launched in September, has fared.

Meanwhile, troubled food manufacturer Northern Foods will also provide an update tomorrow. In November it sold a number of its businesses to Vision Capital for £160m.
