2010 when the previously secret files came to light over the fact that the Medical Research Council was warned that benzodiazepines prescribed to millions of patients appeared to cause cerebral atrophy similar to hazardous alcohol use in some patients and failed to carry out larger and more rigorous studies. The Independent on Sunday reported allegations that "scores" of the 1.5 million members of the UK public who use benzodiazepines long-term have symptoms that are consistent with brain damage. It has been described as a "huge scandal" by Jim Dobbin, and legal experts and MPs have predicted a class action lawsuit. A solicitor said she was aware of the past failed litigation against the drug companies and the relevance the documents had to that court case and said it was strange that the documents were kept 'hidden' by the MRC. Professor Lader, who chaired the MRC meeting, declined to speculate as to why the MRC declined to support his request to set up a unit to further research benzodiazepines and why they did not set up a special safety committee to look into these concerns. Professor Lader stated that he regrets not being more proactive on pursuing the issue, stating that he did not want to be labeled as the guy who pushed only issues with benzos. Professor Ashton also submitted proposals for grant-funded research using MRI, EEG, and cognitive testing in a randomized controlled trial to assess whether benzodiazepines cause permanent damage to the brain, but similarly to Professor Lader was turned down by the MRC. The MRC spokesperson said they accept the conclusions of Professor Lader's research and said that they fund only research that meets required quality standards of scientific research, and stated that they were and continue to remain receptive to applications for research in this area. No explanation was reported for why the documents were sealed by the Public Records Act. Jim Dobbin, who chaired the All-Party Parliamentary Group for Involuntary Tranquilliser Addiction, stated that: The legal director of Action Against Medical Accidents said urgent research must be carried out and said that, if the results of larger studies confirm Professor Lader's research, the government and MRC could be faced with one of the biggest group actions for damages the courts have ever seen, given the large number of people potentially affected.
