A man who accused multiple public figures of child sexual abuse is a “committed and manipulative paedophile”, a court has heard.
Carl Beech has convictions for voyeurism and making and possessing indecent images of children.
Police discovered the offences after seizing devices from his home while investigating him for alleging abuse by public figures, jurors heard.
Beech denies 12 counts of perverting the course of justice and one of fraud.
The 51-year-old’s allegations, which included a claim that three young boys were murdered by members of a group, led to a £2m Metropolitan Police investigation between 2014-2016 that ended with no further action being taken.
Among those accused were former Conservative prime minister Sir Edward Heath, ex-Tory home secretary Lord Brittan, former head of the armed forces Lord Bramall and former Conservative MP Harvey Proctor.
Lord Bramall’s wife died during the police inquiry and Lord Brittan died while under investigation.
Prosecutor Tony Badenoch QC said: “On those devices were found indecent images of young boys, covert images of school boys taken by him, and recordings.
“These child sex offences were committed whilst he was speaking to investigating officers.
“At the same time as he perpetuated these lies about Harvey Proctor and so many others, he was also viewing indecent images of the gravest kind and spying on small boys”, he added.
Jurors heard he installed a secret app on his iPad that appeared to be a calculator, but contained indecent images of young boys of the “most serious kind” and a covert recording of a boy in a toilet.
The court heard he was prosecuted and initially pleaded not guilty, seeking to point the finger at his own teenage son.
The prosecutor said the defendant’s convictions “demonstrates that Carl Beech is a committed and manipulative paedophile, capable of deceit to investigators and limitless manipulation when required, including if necessary, framing his own child”.
He said Beech was “the sort of individual concerned only for himself, unconcerned with the impact on others”.
The trial for perverting the course of justice and fraud continues.
