Margaret Lake, better known as Mystic Meg on television, died at the age of 80.
She was a popular TV personality in the 1990s, appearing on the National Lottery, and she has written horoscopes for the Sun for over two decades.
Lake died in the early hours of Thursday morning, according to the newspaper, after being admitted to the hospital last month with the flu.
“Without a doubt, she was Britain’s most famous astrologer by a million miles,” her agent Dave Shapland said.
“In that regard, no one came close to Meg. Millions of people in this country and around the world followed her.
“She even became part of the English language; if a politician, a celebrity, or an ordinary person on the street is asked a difficult question, they will respond, ‘Who do you think I am, Mystic Meg?”
“It demonstrates the impact she had.”
“This is devastating news,” said The Sun’s editor, Victoria Newton. We’ve lost a symbol.
“For more than two decades, Mystic Meg has been a must-read column, cementing her status as Britain’s most famous astrologer.
“She was a true professional whose advice helped our readers on a daily basis – our postbag attests to this.”
