Prime Minister urges investigation into Waterhouse inquiry following fresh child sex abuse allegations involving senior Tory PRIME Minister David Cameron has ordered an investigation into whether the North Wales child abuse inquiry "properly did its job" following allegations a senior Tory was involved. An inquiry that investigated allegations of historic child abuse in a north Wales care home should be looked at again, says David Cameron David Cameron says action must be taken to ensure "truly dreadful" claims were not left "hanging in the air" Calls for inquiry follow allegations of child sex abuse involving senior Tory grandee Mr Cameron said he was taking action to make sure the "truly dreadful" claims were not left "hanging in the air." The independent investigation will look at whether the Waterhouse Inquiry, held 12 years ago into abuse at the Bryn Estyn children's home in the 1970s and 1980s, was "properly constituted." Steve Messham, a victim of the scandal, claims that a senior Conservative Party figure was among those involved in abuse. Speaking in Abu Dhabi, Mr Cameron said: "These actions are truly dreadful and they mustn't be left hanging in the air. So I am taking action today, first of all to make sure that Mr Messham can meet urgently with the Secretary of State for Wales so he he can hear his allegations and his points directly. Secondly, I am going to be asking a senior independent figure to lead an urgent investigation into whether the original inquiry was properly constituted and properly did its job and to report urgently to the Government. But third, I would also urge anyone who knows anything about these matters to go to the police. That is where evidence should be taken so that action can be taken and we can deal with this dreadful, dreadful issue. In an interview with the BBC's Newsnight last week, Mr Messham claimed that he was taken out of Bryn Estyn and "sold" to men for sexual abuse at a nearby hotel. Mr Messham said a senior Tory from the time, who was not named by the programme, had been involved. He criticised Sir Ronald Waterhouse's inquiry, arguing that its terms of reference meant he was not able to raise the issue of abuse that took place outside the care system. Children's Commissioner for Wales Keith Towler was today expected to write to Welsh First Minister Carwyn Jones to demand an inquiry into the latest allegations. Mr Towler said on Saturday: "I would support a full inquiry. The fact that we have someone on camera now who was clearly a victim of appalling abuse in Bryn Estyn children's home back in the 1970s and 80s, saying that what he wanted to say was outside of the terms of reference, and people told him that he could not say these things and he couldn't talk about people who had abused him, is clearly wrong. The fact that he is now saying that and he has now said it so publicly means we have to respond to that. Mr Cameron's official spokesman today told a regular media briefing in Westminster: "On this issue, it is something that we are looking at actively. The Prime Minister has taken a close interest in the reports and the allegations that have been made. We are very clear that those allegations need to be properly investigated and we need to get to the bottom of precisely what happened. Asked who within Government was looking into the allegations, the spokesman replied: "The Government is looking at this issue. These issues relate to a number of departments, so clearly it is something we are discussing with the Wales Office and the Home Office is involved in these issues too. There are a number of departments that are involved and we at the centre are taking an active interest in the issue and looking at it very closely. Labour MP Tom Watson last month told Mr Cameron at Prime Minister's Questions in the Commons that there was "clear intelligence" suggesting a historic paedophile ring was connected to a former No 10 aide, and called for any evidence to be re-examined. The Prime Minister said he would look at the case "very carefully and see what the Government can do to help give" Mr Watson the assurances he wanted. The Welsh First Minister said he will meet Mr Towler tomorrow to discuss his concerns. Mr Jones said he had requested "urgent advice" on the original remit of the Waterhouse Inquiry, to help him determine whether a further investigation is needed. In a statement today, Mr Jones said: "Serious allegations about child abuse in North Wales during the 1970s and 80s have been made in the media over the weekend, and calls have been made for a fresh inquiry. The Welsh Government takes these allegations very seriously. In the first instance, victims of abuse who feel that the abuse they suffered was not investigated properly should report their cases to the police. My officials have been in touch with North Wales Police. An extensive inquiry into North Wales child abuse - the so-called Waterhouse Report - was published in 2000. It was commissioned - before devolution began - by the then secretary of state for Wales William Hague and reported to Paul Murphy, as secretary of state, in 2000. It made extensive recommendations for improving child protection, many of which were subsequently implemented by the Welsh Government. I have asked for urgent advice on the terms of reference of the Waterhouse Inquiry at the time when it was set up. I need to understand fully what was included in those terms of reference and what was excluded. In due course that will enable me to consider, with others, whether any further inquiry might be necessary.
