Meghan Markle in Camilla's firing line

She’s the wife to the heir of the British throne and now the Duchess of Cornwall, Camilla, is making her position in the royal family very clear.

The 69-year-old, who married Prince Charles in 2005, reportedly doesn’t believe Prince Harry’s girlfriend, Meghan Markle, is fit to be welcomed into the family fold.

According to a report in Woman’s Day, Camilla is doing whatever it takes to make sure Suits actress Meghan and her 32-year-old son-in-law never marry.

"She doesn’t do tantrums, but she has considerable influence,” a palace insider told the magazine.

“If she doesn’t get her way, she leans on Charles and Charles acts.”

The news comes after Meghan’s family has been plagued with controversy in recent weeks.

The actress, who has reportedly been dating Prince Harry for the past eight months, has been under scrutiny after their relationship was made public knowledge.

The star’s 50-year-old brother, Tom Jr, was recently arrested after allegedly brandishing a gun at his girlfriend, Darlene, during a booze-filled argument.

Tom Jr. was arrested and a police investigation into the incident has been launched.

However Markle’s brother has pleaded with his half-sister to forgive him and claimed he would love to be invited to Buckingham Palace if a royal wedding were to take place between the pair.

“If I may say so, Prince Harry has made a few in his time and learnt from them. I just need the same chance,” Tom told the Sun.

“Marriage and kids is on the cards for Meghan and Harry and I still want to go to the wedding if they’ll let me.

“Of course I want to go to London and Buckingham Palace.”

And Tom Jr. isn’t the only family member who’s had a run-in with the law as Markle’s father has reportedly has a long history of debt and filed for bankruptcy last year.

However Meghan’s mother, Doria is reportedly in the good books with the royal family for remaining silent on her daughter’s new relationship.

Camilla hasn’t been afraid to let her feelings be known about her sons-in-law’s romances in the past and she was reportedly behind the reason why Prince William and Kate Middleton split way back in 2007.

At the time it was thought it was due to William’s unwillingness to commit to a relationship, however now it’s been claimed that Charles’ second wife, Camilla, may have orchestrated the whole thing.

According to author Christopher Anderson, who wrote the book William and Kate: A Royal Love Story, Camilla was furious that Kate was “sucking up all the attention” at a time when she was trying to win over the public.

Anderson claims Camilla thought Kate wasn’t worthy enough to be welcomed into the royal family.

In his book, Game of Crowns, he wrote: “Kate is the first working-class woman to be accepted into the Royal Family.

“She is descended from coal miners and her mother was a flight attendant.

“So for all those reasons Camilla never really felt that Kate Middleton as an individual and the Middleton family as a whole were going to be worthy of entering into the Royal Family.

“I was told at the time of the breakup, and later on as well, that Camilla basically whispered in Charles’s ear that it was really time to make—to force—William to make a decision one way or the other.“

However Camilla's plan didn't work and Kate Middleton and Prince William reunited within months.

It's thought Prince Harry is also set to rebel against his stepmother, who he's reportedly had a tumultuous relationship with in the past, and can't wait to marry Markle.

"This new situation with Meghan is doing nothing to help their relationship," a source told Woman's Day.
