I have been asked to reply.
Two inquiries were established under the Tribunals of Inquiry (Evidence) Act 1921 after May 1997: the Shipman Inquiry, chaired by Dame Janet Smith with an estimated final cost of £21 million and the Bloody Sunday Inquiry, chaired by Lord Saville, as yet to be completed and estimated at £160 million.
Since May 1997 public inquiries that have had judicial chairmen include:
The Ladbroke Grove Inquiry chaired by Lord Cullen estimated at £8.6 million;
The BSE Inquiry chaired by Lord Philips estimated at £26 million;
The Ashwoth Special Hospital Inquiry chaired by his honour Peter Fallon QC estimated at £2.5 million;
The Stephen Lawrence Inquiry chaired by Sir William Macpherson estimated at £4.2 million.
