Preparations for King Charles’ coronation are in chaos after rehearsals have been significantly delayed, sparking fears of more pressure on the start of the new monarch’s reign.

With just over three weeks to go until the ceremony, organizers are facing a ‘race against time’ to finalize the details of the King and Queen’s historic coronation at Westminster Abbey.

According to the Mirror, royal aides are working around the clock to ensure everything is perfect for the big day.

However, a list of important issues has emerged at the heart of planning for the May 6 event:

• The seating plan has not yet been arranged, due to Prince Harry and Meghan not yet confirming their attendance.
• There are fears the king could trip over the elaborate robes he will wear in front of 100 million TV viewers.
• Disputes over the route of the coronation, with planners wanting a smaller procession to keep costs down.
• Confusion over whether women will wear tiaras to church, before royal consort enters Abbey
• Prince Andrew’s fury over a possible ban on him wearing the Garter Knight cloak, following his ouster from the royal family.

With just 25 days to go, a sense of panic has gripped the royal family as the clock ticks down for the once-in-a-generation event.

Sources have revealed how the king and queen consort are diligently rehearsing their roles in a specially-built ‘model Abbey’ inside Buckingham Palace.

During a fitting about his elaborate robes, Charles reportedly commented on how heavy they were, leading his aides to express “fears” that he might trip on a walk to the chairs, where he and Camilla sit at the center of of Westminster Abbey after their coronation.

In recent days, master craftsmen have been enlisted to build a ramp up to the two throne chairs so that the king will not have difficulty reaching his seat.

A source revealed that indecision over what tiaras the female royals would wear has also led to disagreements. They said: “Senior female members of the royal family were only informed of the outfits this week, prompting a rush to finalize fitting arrangements.”

As the Mirror revealed last month, the disgraced Duke of York, who was forced to step down from royal duties after being embroiled in a sex abuse scandal which he has vehemently denied, has yet to be told whether he will be allowed to wear the large velvet robes and shining insignia denoting his status as a Knight of the Garter.

The duke last year paid a £12 million out-of-court settlement to his accuser, Virginia Giuffre, and was then prevented from appearing with the late queen in her final appearance in the traditional Garter Day procession in Windsor.

Sources said he was furious when told that as well as not having a central role he might be forced to wear a simple morning suit for his brother’s coronation.

An insider said: “It’s all very frantic, absolute chaos to be honest. There’s a plan, which is supposed to be the plan for how the day should work, but things change every day, which causes huge headaches.”

Other royal sources last night tried to play down the stress, saying: “This is of course a huge event and the important thing is that everyone is pulling in the right direction.

“The king and queen consort want it to be perfect, as does everyone involved, so everything is done to make it so.”

King Charles’ coronation ceremony was originally planned to last 90 minutes – significantly shorter than the late Queen’s coronation in 1956, which lasted three hours and 20 minutes.

Plans seen by the Mirror now show the service starting at 11am. and ends at 12.45pm, with the royal procession leaving the Abbey back to Buckingham Palace at 1pm.
