Speciality foods mainly consist of olives, pickles and olive oils although the number of foods that are classed as being specialities is increasing.

Greek foods are selling particularly well because people have tried the products when on holiday, and people are also buying a lot from Spain and Poland.

Italian foods are experiencing slower sales growth because they are seen as a bit old hat these days.

Sainsbury's has the best range of speciality foods, but Tesco is trying to cover this area more now. There is a big demand for Mediterranean foods and our range is growing.

We originally had 27 Greek lines in 20 Tesco stores but this recently rose to 179 stores.

We also stock three premium lines in 100 of the more upmarket Tesco stores across the country.

Authenticity is also important these days and this is reflected in the types of products that we sell.
