Downton Abbey creator Julian Fellowes has hinted that the next series of the hit show could be its last.

The ITV drama, which tells the story of the aristocratic Crawley family, is set to return to television screens later this year for a fifth series, having started in 2010.

But Lord Fellowes has now said in an interview that the saga will not “go on forever”.

He has been commissioned to write a new American drama called The Gilded Age but told The Wall Street Journal that work on the programme would not start until Downton had come to an end.

Lord Fellowes said: “It's for NBC Universal and it will happen when Downton finishes because I just couldn't do both at once.

"I haven't written it yet, but it's about the old aristocracy, the Winthrops and the Stuyvesants and the new money of oil and gas and shipping in the 1870s. It will all be fiction - it won't be real people - but when those families descended on New York, they took over."

The writer reassured fans that there would be a fifth series of Downton but referring to a long-running US courtroom drama, added: "I don't know yet if there is a season six, but it's not going to go on forever. It won't be Perry Mason."

He also speculated that if the Crawleys had been a real family, they would have still been running the estate today - albeit in a more "businesslike" way.

He said: "My own belief is that they would survive, but they would be living in a back wing - and you could buy a ticket to visit and they would only come out in the winter."

Downton Abbey was last seen on British screens on Christmas Day, when a special episode was broadcast showing the family visiting London for debutante Lady Rose's coming out.
