MOSCOW, July 5 (Reuters) - The Russian broker organising a frozen asset swap scheme said on Friday it had extended the deadline to submit bids until Aug. 2 at the request of non-resident investors.

The previous deadline was July 5.

The scheme, organised by Voronezh-based broker Investitsionnaya Palata (Investment Chamber), could allow Russian retail investors to exchange their frozen foreign securities with non-resident investors who have assets stranded in Russia.
