The head of an abuse charity has said the inquiry into a possible Westminster sex ring in the 1980s "stinks".
Pete Saunders, chief executive of the National Association for People Abused in Childhood, told ITV News letters written by inquiry head Fiona Woolf to the home secretary "greatly bothered him".
It is alleged Woolf amending the letter allegedly playing down her links to Lord Brittan, who is accused of failing to act on the historic abuse allegations, seven times before she sent it.
Mr Saunders said the focus should be on "truth and honesty" and if things like this were happening now Theresa May should "tear the whole thing up and start again".
The investigation into a fire at a fireworks factory in Stafford is 'challenging' because the entire storage unit has been destroyed by the explosion, according to police.
Firefighters and police officers are spending the day recovering any potential evidence from the area around SP Fireworks on Tilcon Avenue.
Last night, two people were hospitalised when a major fire ripped through the factory premises. One victim is in a stable condition, but the other is more seriously hurt.
Police have said they are hoping to reopen Tilcon Avenue to those businesses who have premises on the road and to drivers who need to move their cars in the coming hours.
Baswich Lane has reopened to traffic, but drivers there are experiencing serious delays because of investigation work being carried out by emergency services.
Home Secretary Theresa May will have a "tough job" to replace Fiona Woolf if she steps down as head of the Westminster sex abuse inquiry, the former director of public prosecutions said.
Lord Macdonald said if that happened it would be difficult for May to persuade someone else to take it on.
Woolf is the second person appointed to head the inquiry into the historical allegations.
Baroness Butler-Sloss stepped down from the role in July following concerns about her family links.
Her late brother, Sir Michael Havers, was attorney general in the 1980s when the abuse is said to have taken place.
A 53-year-old man has been arrested in connection with a blaze at a fireworks warehouse, Staffordshire police said.
Police also said that they now believe two people rather than one remain unaccounted for as the investigation continues today.
Murderers Jamie Reynolds, a "sexual deviant" who lured a teenage girl to her death, and former soldier Anwar Rosser, who savagely killed a child, have lost Court of Appeal challenges against orders that they can never be released from prison.
Fiona Woolf is "unqualified" to lead an inquiry into alleged sex abuse in Westminster in the 1980s, critics say.
Pete Saunders, chief executive of the National Association for People Abused in Childhood, said the government should appoint "somebody credible" like 'radical' lawyer Michael Mansfield QC.
Mansfield is said to be the 'abuse victims choice' and has represented the families of Jean Charles de Menzes, shot dead by police in 2005, Mark Duggan, whose death sparked the London riots, and victims of the Hillsborough disaster.
Mr Saunders told BBC 4's Today programme: "If you're going to put together an inquiry into this massive problem, then surely you would appoint a group of specialists who know something about the subject and will have the confidence of the people who are suffering from that particular issue.
"Nobody is having a pop at Fiona Woolf as a person - I'm sure she's a person of high integrity - but she has no qualification whatsoever to lead an inquiry into such a deeply, deeply disturbing issue as child abuse.
"She has said as much, so why should we appoint somebody (like that)?"
