Amenya also criticised Adani for submitting a “privately initiated proposal” for the airport concession, rather than competing in an open bidding process. However, the person close to Adani said it was Kenyan officials who raised the option of bypassing a tender process.

SINGAPORE/SYDNEY, Nov 25 (Reuters) - Adani dollar bond prices fell to almost one-year lows on Monday as investors cut their exposure to the Indian conglomerate in the wake of bribery and fraud allegations from U.S. authorities.

The recent bribery charges by US authorities, made public last week, have led to several countries revisiting or cancelling deals with the group.
