Charles and Camilla got the giggles during a welcoming ceremony in Canada

They couldn't stop chuckling

Words by Jadie Troy-Pryde

We might counting be down the days to our well-deserved summer breaks, but the royal family are currently working very hard.

Prince Harry has just been appointed his first ever official role during a state visit when the Spanish king and queen visit the UK next week, and Prince William and Kate Middleton are getting ready to set off on a European tour with their two children, George and Charlotte.

Meanwhile, Prince Charles and Camilla Duchess of Cornwall spent the weekend on a royal tour in Canada. But rather than piquing the public's interest with their royal duties, it's a clip of Charles and Camilla during a traditional Inuit throat performance that has everybody talking.

The performance, known as katajjaq, is a duet by two female singers who compete to see which singer can last the longest. Traditionally, they face each other and take turns to make noises using inhalation and exhalation techniques. If one performer runs out of breath, laughs or stops, they are out of the competition and someone else usually takes their place.

And when Charles and Camilla were sat watching the performance unfold, they got a serious case of the giggles. Turning to each other and attempting to cover their faces, they were unable to hide the fact that they were laughing.

But the skilled singers were not distracted, and, ever the professionals, continued their performance.

The couple spent three days in Canada, arriving in the Canadian Arctic to start their tour which was organised to celebrate the country's 150th birthday.
