"People can speculate as much as they want, but this will happen," said sales and marketing director Ian Thorpe.

NJP played down its recent Emap loss, worth 3m a year 18% of its business.

"Losing Emap was disappointing, but we're moving on," Thorpe said. "They are gradually phasing out the work, and that has enabled us to refill our presses with six new clients."

NJP was granted planning permission for its super site at Wymondham on 13 January last year, but it has been plagued by delays.

The firm remains confident that the work will progress. "We have solid backing from local investors and deals on the table," Thorpe said.

Despite a condition of its management buy-in that it would have to relocate from its current Whitefriars site, Thorpe said the movement of a 333 staff firm could not be rushed.

"We can remain in parts of our current building until 2010," he said. "The parts where our presses are kept aren't being developed for another four years."

Wymondham (artists impression pictured) remains NJP's preferred location despite the emergence of two other potential sites at Beccles and Snetterton.

NJP has been considering a number of cost cutting options recently including the loss of up to 30 staff and the closure of its London office.

A date to begin work on the new site hasn't been set.
