Jonathan Attwell had been a scout for a month

After reaching the summit and resting at the cafe at the peak of the 3,560ft high mountain, they began their descent down the East Ridge.

They had only gone around 100 metres when Jonathan disappeared from the back of the group.

Mr Findlay returned to the summit, where he told senior mountain warden Sam Roberts that he had lost track of Jonathan.

Body found

Shortly afterwards, an RAF Sea King rescue helicopter found Jonathan's body in a gully.

It emerged later that Mr Findlay's qualifications to run the trip had expired.

Five months after the tragedy, Mr Findlay and fellow leader Mathew Wilson were sacked by the Scout Association after a local management meeting deemed it "inappropriate" that they should continue.

Another Snowdonia tragedy rocked the Scout Association a week after Jonathan's death, when scoutmaster Christopher Oliver, 35, on a trip from Devizes in Wiltshire, died after falling down a gully on Cader Idris.

The inquest into his death heard that Mr Oliver had not been properly equipped for the route he had chosen.

National inquiry

Following these deaths, the Scout Association set up a national inquiry committee to examine safety issues.

If people do not follow our rules, we will suspend them or will withdraw their warrants

Steve Peck, Scout Association

In February 2000, the inquiry reported a "cavalier" attitude to rules by leaders and an "unacceptable" level of risk

It announced "a wide-ranging and comprehensive review" of its outdoor activity rules, including strict adult-scout ratios, and new procedures on authorising expeditions.

Steve Peck, of the Scout Association, said: "If people do not follow our rules, we will suspend them or will withdraw their warrants."

The Association has now told BBC News Online that there has been one further fatality involving British scouts since the inquiry, which a coroner ruled was "sheer bad luck" in a well-organised group.

Voluntary trips

However, outdoor trips organised by voluntary groups still do not require the same licensing rules as commercial organisations.

The Health and Safety Commission (HSC) has advised ministers that such licensing is unnecessary.

But Alun Pugh, AM for Clwyd West believes there should be a national standard for all.

He said: "The dangers are exactly the same. And many parents think if their children are going with a properly organised voluntary group, then certain safety standards will be in place.

"That is unfortunately not always the case."
