Singapore - Singapore's DBS banking group said its chief executive officer Richard Stanley, who was diagnosed with leukemia in late January, is in critical condition. "Stanley's condition has deteriorated rapidly in the last 24 hours and he is now in critical care," DBS said in a filing to the Singapore Exchange on Friday night.

Stanley had been responding well to treatment earlier and after two rounds of chemotherapy his doctors believed earlier this week that his cancer was in remission.

"Unfortunately the unpredictability of the disease has led to severe complications due to infection," said DBS. (dpa)
