Former Eurovision song contest winner Dana is pursuing a landmark prosecution of those who gave false evidence against her brother John.

The Metropolitan Police have sent a file to the Crown Prosecution Service regarding the evidence given by the seven witnesses in 2014 when John Brown was acquitted of five counts of indecent assault against two girls under the age of 13 and 16.

The charges being considered against the seven include attempting to pervert the course of justice and perjury.

Mr Brown, 61, a father-of-three who works in PR and the music industry, had denied all the claims.

His older sister, 67, a former Irish presidential candidate, was accused by the prosecution of covering up her brother's abuse for more than three decades.

Mr Brown said it had been a 'horrendous experience' for his family', adding that 'both Dana and I were put on trial.'

If the CPS chooses to prosecute, it will be the first time witnesses in a historical sex abuse case have faced trial for making false accusations, the Sunday Times reported.

It would also increase the pressure to charge the 'credible and true' witness known as 'Nick', whose claims of a Westminster VIP paedophile ring led to the £2.5m Operation Midland inquiry which collapsed when he was outed as a fantasist.

Mr Brown has been backed by celebrities who have also been the subject of false sexual abuse allegations.

Louis Walsh, a judge on the X Factor, offered his backing to the 61-year-old.

He said: 'I have known Dana and John for many years. I fully understand the terrible time they went though.'

The family have also received support from Sir Cliff Richard, who was the subject of a two-year inquiry into alleged historical child abuse offences in Britain before the case was dropped.

He said: 'I would like to join the growing band of people who, like me, have been put through the most agonising emotional trauma and I pray that together we, with Dana and John , will eradicate that destructive act known as 'a false accusation'.'

Paul Gambaccini, the BBC DJ who was arrested but never charged under similar allegations, added: 'No man can acquiesce in his attempted annihilation. I fully support John Brown and Dana and urge them to see their legal action through to its conclusion.'

The Met are scheduled to have a meeting with the CPS to discuss the case within the next few weeks.
