One of the best-known names in UK industry has disappeared from the stock market after Marconi completed the sale of most of its assets to Ericsson.
The Swedish company secured the Marconi trademark as well as 6,660 of the company's employees in the sale, which was first announced in October.
The remainder of the Marconi business has been renamed Telent, with the change taking place yesterday on the London Stock Exchange.
Ericsson, which picked up Marconi's expertise in network equipment technology through the deal, has yet to decide what it will do with the company name.
An Ericsson spokeswoman said: "The brand is part of the deal and we will use it in some way, but how we are still investigating."
Around half of Marconi's 4,000-strong workforce in the UK will switch to Ericsson.
Staff transferring from Marconi plants at Coventry, Beeston, Liverpool and Chorley, have received letters from the company's chief executive Carl-Henric Svanberg welcoming them to the business.
But former Marconi staff face an uncertain future as Ericsson expects a reduction of between 15 to 20 per cent in the combined workforce.
The services arm being retained as Telent will utilise other staff at Coventry, as well as sites at Basildon and Chorley. Its customer base includes BT, Cable & Wireless and TV cable firm NTL.
The assets sale to Ericsson wrote the final chapter for a company which traced its roots back to 1885 when Italian Guglielmo Marconi managed to transmit a signal over a distance of about 1.25 miles.
The subsequent business became part of General Electric Company in 1968, but fell on hard times after a number of acquisitions and the sale of Marconi Electronic Systems to British Aerospace in 1999.
In the end it found itself too small to compete with the likes of Ericsson, which will now be able to bolster its position in the transmission segment.
