What is 'gag gifts' tradition in royal family on Christmas?

The British royals love receiving cheeky gifts on Christmas and these presents are a rare chance for ‘laughter and levity.’

According to a report by the Radar Online, the royals exchange rudest and weirdest presents as part of the family’s 'Gag Gifts' Tradition .

The weirds gifts of Meghan to Prince William, Kate Middleton to Prince Harry and Princess Anne to King Charles have been revealed.

The insider said, "It's a chance for the royals to be playful, enjoy each other's company, and have some fun – even if it's just behind the palace walls."

A senior palace aide said, the Sandringham estate is the backdrop for the playful exchanges.

The insider said, "Each family member has a small stack of gifts arranged on trestle tables. Most are inexpensive and meant to make people laugh rather than impress – instead, it's about the royals teasing each other and having a bit of naughty fun.”

There are reports, Kate Middleton once gave Prince Harry a 'Grow Your Own Girlfriend' kit before the duke met Meghan Markle.

Meanwhile, following her engagement to Prince Harry, Meghan Markle said to have handed a spoon embossed with the words "cereal killer" to her brother-in-law Prince William during her 2017 Christmas.

The 'gag gifts' tradition dates back decades.

A royal historian tells the outlet, "The presents are usually set out on Christmas Eve and exchanged around teatime.”

The expert went on saying it works well since everyone is up early for the service at St. Mary Magdalene Church the royals traditionally attend, with proceedings then moving on to various family activities.
