BBC TV presenter Selina Scott reveals in 'The Sunday Times' that the millionaire chased the Princess of Wales with flowers for a long time.
"He bombarded Diana at Kensington Palace with massive bouquets of flowers, each worth hundreds of pounds. Trump clearly saw Diana as the ultimate trophy wife," she writes in the newspaper's 'News Review' section.
"As the roses and orchids piled up at her apartment she became increasingly concerned about what she should do. It had begun to feel as if Trump was stalking her," she recalls.

"Just throw them in the bin," I advised. Diana laughed.
Scott adds: "When she died in the tragic accident in Paris in 1997 Trump told friends his biggest regret was that they hadn't dated. He said that he always thought he had a chance of romance and would have had a 'shot' with her."
In his 1997 book, 'The Art of the Comeback', Trump wrote: "I only have one regret in the women department - that I never had the opportunity to court Lady Diana Spencer. I met her on a number of occasions. I couldn't help but notice how she moved people. She lit up the room with her charm, her presence. She was a genuine princess - a dream lady."
The veteran television presenter and interviewer also writes about the vitriolic letters the US property tycoon wrote to her for many years after she made a critical film profile of him.
"Ultimately, I made it clear to him that if he continued to harass me I would take legal action against him. The letters then stopped," she said.
