Dallaglio was England captain immediately before Johnson, leadingthe team in 14 matches before newspaper allegations of recreational drug use,which he always denied, forced him to resign from the post in 1999.
In a statement, England coach Clive Woodward said: "I wasin the fortunate position of having a lot of outstanding players to considerfor the captaincy role, to follow in the footsteps of Martin Johnson who wasalways going to be such a hard act for any player to follow, both on thepitch and in his leadership qualities.
"Many players have proven to me they could do the job but inmy opinion Lawrence is the stand out choice for Italy. I'm really pleased forhim and I am confident he will be excellent in the role."
But Woodward stressed that his decision to appoint Dallaglio tothe captaincy did not mean the 65-times capped forward was in permanentpossession of the job.
"As always I will be appointing the captain on a game by gamebasis, a philosophy I've maintained since I've been in charge," Woodwardsaid.
Meanwhile a delighted Dallaglio, whose father is Italian, said:"I'm very pleased to accept this responsibility. It's a huge honour and privilege and Martin has certainlyset a high standard. He is a world class player and is a great loss to Englandbut I respect his decision to retire," the British and Irish Lionsstar added.
"All teams move on and evolve and England is no exception.The priority is to get selected on form, that's paramount. I see playing well as thekey to
"I want to continue to work closely with Clive and thecoaches and take England to the next level. But we are under no illusions. As worldchampions it will be a huge challenge to achieve that goal but it's one I knowwe all share."
Meanwhile, veteran lock Fabien Pelous, whois to succeed Fabien Galthie as captain of France, was back in trainingWednesday for his club Toulouse over three weeks after twisting a knee.
"It went well even if I'm a little short of breath,"said Pelous after the two-hour session. His chances of recovering full fitness in time to turn out forFrance against Ireland in the Six Nations Championship on February 14th lookto have improved after his trouble-free return to training.
He said: "I want to wait two days to see how it goes, but I'dsay I'm 50-50 to play in the match (for his club Toulouse) on Saturday."
The 30-year-old, capped 86 times, has already said he wants tocarry on to the 2007 World Cup.
Pelous captained France 15 times between 1997 and 2002 and tookover from Galthie when the scrum-half was injured for the last three matches ofthe 2003 Six Nations.
Pelous picked up his injury minutes after coming on as a secondhalf substitute against Biarritz on January 3. His return to the pitch will be welcome news to France head coachBernard Laporte as he deals with a second row injury crisis for the Irelandmatch involving Olivier Brouzet, recovering from a collarbone operation,David Auradou, carrying a calf strain, and Jerome Thion, suffering from anAchilles tendon injury.
Pelous' club teammate, France centre Yannick Jauzion, also resumedtraining Wednesday after a calf injury. The three-try scorer for france against Fiji at the World Cup lastyear who was forced to sit out last weekend's game against Leeds in theEuropean Cup said: "I didn't feel any adverse reaction. I'm ready forSaturday."
