A mark of the impact Kultida Woods forged on the record-breaking career of her son, Tiger, was provided by the fact the US President led the tributes after the 80-year-old unexpectedly died on Tuesday morning.

Tiger Woods says that his mother, Kultida, has died at age 80. The golfer credited her for his success and encouraging his signature look of red shirts.

Kultida Woods, the Thai-born mother of Tiger Woods who instilled his dominant spirit and encouraged him to wear a red shirt on Sunday as his power colour, died Tuesday.
