July 28 (Reuters) - Britain's FTSE 100 .FTSE index is seen opening lower on Wednesday, with futures FFIc1 down 0.2%.

* INFLATION: British retailers cut their prices more heavily this month than in June as supermarkets intensified their battle for customers, an industry group said, offering some relief to shoppers as broader inflation accelerates.

* BHP: London's Court of Appeal made a U-turn on Tuesday by agreeing to reopen a $7 billion lawsuit by 200,000 claimants against Anglo-Australian mining giant BHP BHPB.L , reviving a case over a dam rupture behind Brazil's worst environmental disaster.

* SHELL: Royal Dutch Shell RDSa.L said on Tuesday it would buy renewable energy retailer Inspire Energy Capital LLC, as the European major looks to expand its renewable power business in the United States.

* RIO TINTO: Britain's financial watchdog is conducting a probe into Rio Tinto RIO.L and its $6.75 billion underground copper project in Mongolia's Gobi Desert, the Financial Times reported on Tuesday.

* RIO TINTO: Rio Tinto RIO.AX said on Tuesday it would invest $2.4 billion to develop its Jadar lithium project in Serbia, bringing forward an investment decision that was expected later in 2021, as demand for electric vehicle batteries is on the rise.
