Coronation Street's upcoming tram crash plot is costing ITV more than £5m, it has been claimed.
According to the News of the World, the logistics of the live show mean that much of the set will be demolished and rebuilt twice, costing £4.23m - making it the most expensive soap storyline ever.
A source said: "We wanted to celebrate our 50th anniversary in style - and doing that doesn't come cheap.
"It'll be the most expensive plot ever screened on British telly. But we reckon our viewers will think it's money well spent and a good way to start our next 50 years."
Meanwhile, £188,000 will be spent on salaries, catering and costumes, experts and stunt co-ordinators will cost £285,000 and a further £187,000 will go on safety precautions. Services from special effects experts have also come to £245,000, making a grand total £5.3m.
