UK Prime Minister's awkward curtsy to Prince William leaves Twitter in stitches

British Prime Minister Theresa May has hit the headlines again for the curtsy she rolls out for members of the Royal Family.

Instead of an elegant bob, May's curtsy looks more like a crooked lunge, leaving the Duke of Cambridge looking a little nonplussed outside Amiens Cathedral in Northern France this week.

And while it's not the first time the UK PM has been mocked for her awkward royal greeting, Twitter erupted in memes.

"An hour later and Theresa May is still trying to unravel herself after curtsy," one person captioned a photo of an ice-skater twirling.

While another person tweeted: "Theresa May is the only person I've ever seen who can make a curtsy look offensive."

One woman called labelled the leader as "an embarrassment", saying: "Who the hell taught her to curtsy! She looks an embarrassment! I mean this is the Elite at its worse!!"

While another claimed: "Prince William tries not to laugh at Theresa May's curtsey (sic)."

According to English etiquette bible Debrett's, women should curtsy when being introduced to a member of the Royal Family, then again when they leave.

It states, "To make a curtsy briefly bend your knees with one foot forward", a movement the PM seems to struggle with.

In June, May treated William to a similar display at a ceremony at the Defence and National Rehabilitation Centre with her long legs splayed out awkwardly.

While The Duchess of Cambridge and The Queen have also been on the receiving end previously.

May is not the first politician to over-egg her curtsy. Margaret Thatcher habitually dipped almost to a crouching position while greeting the Queen.

Former Australian Prime Minister and staunch republican Julia Gillard decided to swerve the curtsy altogether when she met the Queen in 2011, shocking protocol experts by opting for a swift bob of the head and a hand shake.

Men get off lightly when it comes to royal protocol and are merely required to bow.
