ENGLISH RFU officials will leave, Jason Leonard's fate in the hands of a Five Nations investigation into with the player's alleged punch on Scotland captain Rob Wainwright in Saturday's Calcutta Cup clash.

Leonard will be dealt with by a commission that is due to sit in London tomorrow after Scottish officials cited him for his act, which was captured on television during a maul.

RFU secretary Tony Hallett said: "We are taking no further examination or imposition on Jason. We have allowed the matter to go forward to the Five Nations.

"There was no discussion on Saturday night and we were not informed that Scotland would be citing until just before the deadline."

England manager Jack Rowell said: "Citing is relatively new and we will work through the experience of these incidents, but this is the way rugby is going.

"Once it's under way we must go along with the process, but this has already become a cause celebre."

Hallett added: "We will not be going down the retaliatory path of viewing the tape to cite Scots or other countries for incidents.

"In January, we did ask the French to examine the conduct of their centre Richard Dourthe, and they took appropriate action."

Leonard's alleged punch preceded treatment for Wainwright, but there are two factors in his favour.

First, he has only to show that he should be treated in the same way as if the referee had seen the incident. A similar episode occurred at Murrayfield when World Cup final referee Derek Bevan merely penalised Scott Hastings for landing a punch on Martin Johnson - no yellow card, no warning.

Also, in citing cases a presumption of innocence is there at the start. But the climate is against Leonard.

Dourthe and Irish prop Peter Clohessy have been banned during this Five Nations campaign, although their acts of foul play were far worse in that they involved the boot.

If Leonard is to be suspended the recommended ban is 30 days, which would cost him the chance of appearing in the Triple Crown decider against Ireland at Twickenham.

Meanwhile, England manager Jack Rowell is promising "excitement and ambition" when England tackle Ireland. Rowell remains optimistic that England's style will finally he turned on at the final hurdle after a season of success and media criticism in equal measure.

However, Rowell is not so confident as to predict another Five Nations' Championship for England.

"France's points difference is 21 better than ours and as such it is not being realistic to go for the championship.

"Though if we cut loose, who knows what will happen at Twickenham and Cardiff; where the French play Wales."

Rowell will be naming his team to play Ireland later in the week and will be waiting to see whether Leonard is suspended.

Victor Ubogu has been the understudy prop, but if Rowell is looking to the future, Leicester's uncapped Darren Garforth might be a candidate if Leonard is stood down.

Rowell said: "We would like to build on the 18-9 win in Scotland, adding to the collectivity and unity and perhaps bringing in some excitement.

"We have got to focus on winning the game, achieving the same amount of possession and going into the match with definite ambition."

Despite England's tryless display in crushing the Scots, Rowell expressed the pleasure and emotion from within the camp.

"I was immensely proud of the effort put in by the team in front of 60,000 hostile fans.

"They welded together when the intensity and tension was overwhelming, especially when there was only one score in it.

"There were moist eyes from the captain Will Carling and Dear's Richards. They are experienced but that is a measure of how much the win meant.

But Rowell is committed to finding a new Richards in the near future and also re inforcing the quality of England's stand offs.

"The Richards effect in Five Nations' rugby does need duplicating but so far nobody has come forward."
