Queen Made 'Greased Brakes' Remark After News Of Diana's Crash

Following the news that Princess Diana had been in a car crash, Queen Elizabeth gave what the author of a new royals biography called an "astonishing remark."

A source for the new book says the Queen — not yet knowing the severity of the accident that killed her daughter-in-law — said, "Someone must have greased the brakes."

Ingrid Seward is the author of "The Queen's Speech: An Intimate Portrait Of The Queen In Her Own Words," scheduled to be published at the end of the month.

In excerpts printed by the Daily Mail, Seward wrote the greased brakes remark "reveals something of the extraordinary and complex relationship between her and Diana."

It'll probably do anything but pacify Diana enthusiasts. Despite her long-time separation and divorce from Prince Charles, the Princess of Wales was one of the most beloved royals when her car crashed in an underground tunnel in Paris in 1997.

The second in line to the throne is now allowed access to the income accrued on the 6,5 million pounds he was left in his mother's will after she died 10 years ago in a car crash in Paris.

"Within the last few moments, the press association in Britain — citing unnamed British sources — has reported that Diana Princess of Wales has died," BBC's anchor said the night of Diana's death.

Since Diana's death, blame and debunked conspiracy theories have been abundant. Some blamed paparazzi following Diana's car, French authorities said her driver was intoxicated and the father of Princess Diana's boyfriend claimed British special forces murdered the princess.

After getting over the shock of Diana's death, Seward says the queen's first thought was on Princes William and Harry.

"She wanted the family to stay in Scotland to give her grandsons a chance to absorb the shock of their mother's death as far as possible from the public eye."
