Israeli retailer Blue Square has posted a 5% rise in first-half sales thanks to contributions from new stores opened in the last six months.

Blue Square, which operates 181 outlets in Israel, booked revenue of NIS894.9m (US$210.6m) for the period to 30 June.

The company saw operating income rise by 2.6% to NIS154.7m as higher costs linked to the store openings weighed on the increase in sales.

The retailer also named Zeev Kalimi as president and CEO. Kalimi will join Blue Square from Israeli dairy group Milko Industries.
