LISBON, Oct 25 (Reuters) - Portuguese retailer Jeronimo Martins on Wednesday posted a 28% jump in third-quarter net profit, driven by a robust sales increase at its market-leading Biedronka chain in Poland.

The company reported a net profit of 202 million euros ($214 million) between July and September.
