“This is because – so far – she has managed to tread the very fine line of creating interest that is positive but not unmanageable.”
Sophie and Kate have attended many events together in their senior royal roles.
Earlier this year, prior to lockdown, they were spotted at Buckingham Palace as Kate hosted a reception.
On such occasions, Sophie appears to watch out for the Duchess, showing why Kate might look to her for guidance.
