While the show typically airs at 8pm on Sunday night, tonight it won’t be on the BBC.
Glastonbury Festival coverage will see the BBC air Kylie Minogue’s set broadcast between 6pm and 8pm.
Subsequently, Countryfile is also airing in the later-than-usual slot of 8pm.
Fiona Bruce and the Antiques Roadshow experts will be back next Sunday.
The synopsis for the episode reads: “Fiona Bruce and the team head to Helmingham Hall in Suffolk, which has been home to 20 generations of the Tollemache family.
“The moated Tudor manor house, with two working drawbridges, is the perfect backdrop for a roadshow brimming with antique finds.
“Lee Young discovers a collection of 17th- and 18th-century decorative boxes that the owner is using as his pension fund.
“Militaria specialist Bill Harriman is intrigued by a medieval sword dredged up from a pond on a golf course, and Geoffrey Munn sees an Indian jewel, dating back to the Siege of Seringapatam in 1799, that carries a jaw-dropping value.”
Last week’s instalment of the programme saw one visitor to the Roadshow completely shocked by the value of their painting.
The guest brought along what he believed to be a copy of a painting by William Orpen which hangs in the Imperial War Museum.
He explained: “The story is quite interesting, it started off being called the spy and then he changed his story and called it the refugee but then it turned out that is wasn’t either of those.”
The guest continued: “He was doing a job and he sort of slipped this one in and it turned out this was his mistress and he got into a lot of trouble over this because he was doing a bit of private work when he should have been doing war work.”
Expert Rupert Maas then declared he thought the painting was in fact a work by Orpen.
He remarked: “I think the light in her eyes are brilliantly done and the highlights in her hair really work.”
“I’m all excited now, all the time we’ve had it in our family we all assumed it was a copy,” the guest shared.
Rupert clarified that the painting was a still a copy but if it turned out Orpen was the artist, it could fetch between £20,000 to £30,000.
“Goodness gracious me is about the mildest thing I could say!” the contributor exclaimed.
In another segment, Rupert and the guest were joined by the original artwork and the copy.
It was revealed that Orpen experts had “no doubt in their mind” it was by the man himself.
Rupert then revised his original valuation to deliver the staggering news that it would be worth £250,000.
Antiques Roadshow continues next Sunday at 8pm on BBC One.
