Robert Lacey has recently written about the relationship between the two princes entitled ‘Battle of Brothers’. He claimed in an interview this month the brothers have been treated differently their whole lives and it was William who was treated more kindly. He added that Harry follows in the tradition of "spares" like Princess Margaret and Prince Andrew who were “treated harshly by the royal system that favours the main bloodline”.
In other words, these royals were close to the centre of attention when they were young and were then gradually pushed outwards as they went down the line of succession.
For example, in Harry’s case, he was third in line to the throne when he was born but after William had children, he was pushed down the line and therefore made less relevant.
Similarly, Princess Margaret used to be right after her sister in the succession to the throne, but at the time of her death, was below the Queen's four children and six grandchildren.
The "spares" have also struggled with their role, which is not clearly defined, unlike their older siblings who are destined to become monarch, Mr Lacey claims.

He added this has led to them receiving more of the blame for things that were not entirely their fault.
Pod Save the Queen is hosted by Ann Gripper and features Daily Mirror royal editor Russell Myers.
Mr Lacey made his arguments in an interview with Ms Gripper earlier this month, outlining how he tried to put across this theme in his book.
He claimed: “I try to show in the book the way in which the royal system has treated these two boys in different ways.
