While the source is confident that these concepts are happening, the theme park is not expected to open until 2031, which means some plans could change.

Attractions based on JK Rowling's characters and settings are a popular feature of other Universal resorts.The source told the BBC that "watertight exclusivity contracts" made it difficult to include Hogwarts in the plans, although it could be reconsidered alongside other brands such as Nintendo or Wicked if the park were to expand in the future.

"Warner Bros has the UK rights to Harry Potter attractions. They tried to find a way round it but couldn't. That could change in years to come, though," the source said.Warner Bros Studio Tour has been invited to comment.Universal Destinations and Experiences is expecting 8.5 million visitors a year at the park.

Transport links close to the site will require significant improvements to accommodate the new arrivals, which the government says it is committed to.Universal previously described the site as "an ideal location with convenient, fast rail links to London and London Luton Airport".

The borough's mayor, Tom Wootton, a Conservative, said: "Bedford is the perfect place for this investment – well-connected, full of talent and ready to grow.

"We're proud to be chosen as the home of Universal in the UK. I'm delighted that our residents and communities will benefit in the years and decades ahead."Nic Noble raised around £1m for the new centre in honour of her sister, who died from cancer, and was there for the Royal visit.

She said: "Luckily my mum was presented to her [the Queen] which for me it was a joy - she had a nice conversation with her."She added that the Queen is "just such a lovely lady. She was down to earth, she put everyone at ease."

Ms Noble's mother, Diane Young, said she spoke to the Queen about how "terrible" the facilities the new centre has replaced were."We spoke about how this is a marvellous new centre, that I was so proud of Nic and her late sister. She was very approachable and obviously impressed with the new centre," she added.
