Kate Middleton, Meghan Markle 'dynamic has become poisonous'

A royal insider has claimed that the ‘dynamic’ between Kate Middleton and her sister-in-law Meghan Markle has become ‘poisonous.’

Speaking to the Radar Online, the source claims, "The dynamic between them has become poisonous," with the royal observers also noting not even Middleton's recent cancer diagnosis has prompted a reconciliation.

The outlet also claimed the Princess of Wales had made repeated efforts to help Meghan adjust to life within the royal family – before the duchess burned all her bridges with The Firm.

The publication, citing the royal insiders, claimed Kate declared: "I wanted Meghan to feel welcome and supported. It's never easy stepping into this world and I once stood in her shoes."

Reacting to these claims, royal expert Rebecca English says, Middleton, with support from Duchess Sophie, made multiple attempts to help Meghan integrate into the royal fold.

The expert claimed both Kate and Duchess Sophie checked in on Meghan, particularly after the birth of her son, Prince Archie.

Earlier, the BBC had reported Harry and Meghan had reached out to the Prince and Princess of Wales following the announcement of Kate Middleton’s cancer diagnosis.

Prince Harry and Meghan had also said they wished "health and healing" for Kate.
