Thatcher did indeed play a part in the cover up. Dougkas Hurd wanted to reveal it all after Lord Justice Taylor's report (from the Liverpool Echo)
"She (Thatcher) was told in a memo from a senior civil servant the interim report found the chief superintendent in charge at Hillsborough “behaved in an indecisive fashion” and senior officers infuriated the judge by seeking to “duck all responsibility when giving evidence” to his inquiry.
The memo made clear Mr Hurd thought South Yorkshire Chief Constable Peter Wright would have to resign, adding: “The enormity of the disaster, and the extent to which the inquiry blames the police, demand this.”
It added: “The defensive, and at times close to deceitful, behaviour by the senior officers in South Yorkshire sounds depressingly familiar.”
But Mrs Thatcher made clear in her handwritten note she did not want to give the government’s full backing to Lord Taylor’s criticisms, only to the way in which he had conducted his inquiry and made recommendations for action.
She wrote: “What do we mean by ‘welcoming the broad thrust of the report’? The broad thrust is devastating criticism of the police. Is that for us to welcome? Surely we welcome the thoroughness of the report and its recommendations – M.T.”
