NEW images of the King's Coronation concert have been released and the staging has caused a mixed reaction. 

The mock pictures from the BBC depict a Union Flag-shaped stage which fans out to the live audience gathered for the historic show at Windsor Castle.

The concert, held on Sunday, May 7, will celebrate the crowing of the King and Queen Consort and has a stellar line-up. 

Around 20,000 people are expected to attend the regal occasion hosted by Paddington Bear and Downton Abbey actor Hugh Bonneville.

Against the background of the East Terrace of Windsor Castle, the stage is lit-up in the classic Union Flag colours of red, white and blue.

There are multiple levels for the 74-piece classical ensemble formed from the strings of the Countess of Wessex’s String Orchestra and woodwind, brass and percussion sections from the Bands of the Household Division, the BBC has said.

With the parapet wall steps in the middle and four additional catwalks, they come together to make an abstracted Union Jack.

Following the release of the mock images, Brits have flooded Twitter with their thoughts.

One fan posted: "Looks Amazing!!! #Coronation #CoronationConcert."

A second user commented: "Wow, grand and beautiful."

While a third posted: "This looks soooo cool. What a stage! #Coronation #CoronationConcert."

Meanwhile, other users disagreed and also shared their views on the social media platform.

One person said: "Bit over the top, methinks. Brexity types are gonna love this.."

A second user added: "Waste of money."

While a third joked:" The second one looks like an alien invasion."
