Queen Elizabeth II had a complicated relationship with one of the prime ministers she has worked with throughout her time as the head of the monarchy. This week, she will be meeting the 14th prime minister during her reign.

In the book “The Queen and Di: The Untold Story,” royal author Ingrid Seward said that Her Majesty became fearful and profoundly troubled over how former Prime Minister Margaret Thatcher handled the miners’ strike from years ago.

The Queen also became extremely concerned with the direction that the country was undertaking at that time. And to make things worse, the monarch and Thatcher also shared very different views about a lot of things, which makes them diametrically opposed politically.

“Their differences carried through into politics; whereas the Queen believed wholeheartedly in compromise and concession, Mrs. Thatcher was guided by the incandescent light of zeal which brooked no opposition,” Seward said.

Rumors of a feud between the two high-profile individuals circulated when Thatcher was still the prime minister because it was very rare for the Queen to have to deal with a female PM. In fact, she had almost only dealt with the much older male PM that she immediately hit it off with professionally.

But in Thatcher’s book, she denied that she and the Queen were ever at odds with each other. In fact, she hinted at the possibility that the stories about their alleged feud were simply made up.

However, there was an alleged instance wherein Thatcher rang the palace to ask what color the Queen would be wearing to an event that they were both attending. Shortly after, a palace staff gave Thatcher a response that came from Her Majesty.

“Don’t worry, the Queen never notices what other women are wearing,” royal expert Judy Wade told Express.

But after Thatcher resigned, the Queen once again silenced rumors of a feud. She immediately gave Thatcher the Order of Merit and the Lady of the Garter recognition.
