The King was joined at church at Sandringham on Sunday by his younger sister the Princess Royal – who wore a casual bobble hat for the occasion.

The Princess Royal, who made headlines at the Paris Olympics this summer after making her public debut in a bucket hat, chose a navy blue woollen hat with large bobble for the stroll to church.

The siblings remain at Sandringham after the Royal family’s Christmas gathering, during which dozens of the family members met the public on their way to church on Dec 25.

The Queen did not make the journey for Sunday worship, with the Prince and Princess of Wales and their young family opting to stay at nearby Anmer Hall.

There was no sign of the Duke of York, who did not attend the Christmas Day event after being embroiled in a fresh scandal over an alleged Chinese spy.

Dozens of well-wishers gathered on the route to St Mary Magdalene Church in Sandringham to greet the royal figures.

The King and Princess Royal stopped to speak to Rev Canon Paul Williams outside the church before the service on Sunday morning.

The King carried an umbrella, wearing a thick coat over tailored trousers. The Princess Royal wore a winter jacket and pleated skirt, with a vivid red scarf and dark blue hat covering her usual pinned hairstyle.

Elizabeth II used to prefer staying at Sandringham, in Norfolk, throughout January, making her accession day – also the day her father died – on Feb 6 there.

The King and Queen have altered that tradition to spend much of the month in Scotland, and will travel to Birkhall in the coming days.

The King and Princess Royal have a close relationship, with the latter raising a smile when she called her elder brother “old bean” on camera as part of a documentary about his coronation.
