Every family has its drama and the Royal Family is no different.
Upcoming Channel 5 documentary 'The Royal Family At War' is set to shed the light on a feud most families can relate to.
According to royal experts, the Prince of Wales is not the Queen's favourite son.
As the monarch's first born, Prince Charles is the heir to the throne and now takes on many of her royal duties.
But the experts claim Prince Harry and William's father does not hold that special place in Her Majesty's heart, The Mirror reports.
Out of her five children: Charles, Prince of Wales, Anne, Princess Royal, Prince Andrew, Duke of York, Prince Edward, Earl of Wessex - it is apparently controversy marred Prince Andrew who wins the 'best son' medal.
The politics of the family is explored in the new Channel 5 show, which claims this favouritism is believed to have caused a feud between the brothers that time has not healed.
Eleven years younger than his older brother, Andrew was born while Charles was at boarding school in Gordonstoun, an experience he is said to have hated.
After they finished school they both enlisted in the Royal Navy. Charles spent five years as a captain and Andrew also joined - but Andrew's career got far more attention.
As a helicopter pilot at 22 Andrew was sent to the Falkland Conflict and on his return he was greeted by his mother The Queen, as his ship pulled in.
Katie Nicholl said: "He came back a hero and was very much the golden boy of the royal family."
Experts believe the Queen has long felt the weight of raising Charles to be the next king - but with Andrew she is said to have a far more hands on relationship.
Royal author, Katie Nicholl told the documentary: "There is real tension between Charles and Andrew. Andrew has a very different relationship with his mother and the Queen was much more hands on."
Journalist Penny Junor said: "I think the Queen has always had a bit of a blind spot when it comes to Prince Andrew."
In 2011, Prince Andrew stepped down from his position as UK trade envoy following criticism over his friendship with late American billionaire Jeffrey Epstein.
In December 2012 Prince Andrew took the unusual step of releasing a statement to the press insisting there was no feud between the brothers.
It said: "There is no truth to the story that there could be a split between the Prince of Wales and I. Any continued speculation is pointless."
But rather than quash the rumours, it only served to add fuel to the fire.
Kate Nicholl said: "It's very rare for them to deny something like sibling rivalry. There's no smoke without fire and by denying it, he was fuelling to speculation. It's clear there were problems between the brothers."
The Royal Family At War is on Channel 5 at 10pm tonight.
