The late Queen grew to really trust the Princess of Wales with the pair sharing a ‘grandmotherly bond,’ experts have told a new documentary.

The Princess saw her husband’s grandmother as a ‘guide’ when she joined the royal family.

Speaking in the documentary “Kate & The Queen: A Special Relationship” broadcasted on Channel 5 the Daily Mail’s editor-at-large Richard Kay explained how the pair ended up with a special bond.

The queen grew to trust Catherine. I don’t think she really trusted anyone on first impression, we’re all performing the same show, the show is supporting the Queen.

‘But with Catherine and the Queen it grew deeper than that, there was a real grandmotherly affection between the two’.

Ingrid Seward, royal expert and editor of Majesty magazine echoed his comments, adding: ‘I think the Queen saw her strength and saw that she is a caring person who had this amazing affiliation to duty.

Right from the beginning, Princess Catherine had a lot more in common personality wise with Elizabeth.

‘They have something about them which has that inner poise and the capacity to lead and command respect,’ she added.

India McTaggart, royal correspondent at the Telegraph, added: ‘Catherine has said the Queen was very supportive of her as she was undertaking her first engagements without William. I think she influenced her by showing her by example.’.

Finally, royal expert Victoria Murphy added that Catherine always described the Queen as ‘a gentle guidance’. ‘I think Catherine would have really appreciated the kindness and attention the Queen had given to her, and she knows better than anyone how busy the Queen is. She put time aside to make Kate feel appreciated.’
