Guilty or not guilty? Don't miss the chance to pass YOUR verdict on Lord Lucan in the Mail's exclusive poll

It shot straight to number one in the true crime charts – and today the Mail's ground-breaking podcast, The Trial of Lord Lucan, enters its most thrilling phase.

From 6am on Friday morning, we are inviting you, the listener, to join the jury and seal his fate.

It has been an extraordinarily successful week for the Lucan podcast. Barely a week ago, no one had heard a single episode – yet within days it incredibly seized second place in the charts for all UK podcasts.

In a world-first, the team behind the Mail's acclaimed series has brought to life the case against the infamous earl. 

Every day this week, new episodes have chronicled how Lord Lucan's actual Old Bailey trial might have unfolded had he been caught.

Presented by the Mail's Associate Editor Stephen Wright and broadcast journalist Caroline Cheetham, it is based on a never-before-seen, 60-page Scotland Yard document obtained exclusively by Wright, setting out the evidence amassed by detectives in the 1970s.

And to lend it the gravitas it deserves, two of Britain's most eminent barristers have presented the prosecution and defence cases in enthralling detail. But now it is time for listeners to decide Lord Lucan's fate. 

Until midday on Sunday, votes can be cast to determine his guilt or innocence before the verdict is revealed in a special episode at 6am on Monday.

The drama has gripped audiences just as the world was captivated by the unsolved murder 50 years ago.

The mystery scandalised Britain when Lord Lucan went on the run after the family nanny, Sandra Rivett, 29, was bludgeoned to death with a lead pipe in the basement kitchen at the Belgravia mansion, and the earl's estranged wife, Veronica – believed to be the intended victim – sustained serious head injuries before fleeing.

Jamie East, the Mail's head of podcasts, said: 'The most exciting part is yet to come. The listeners must weigh up what they have heard and cast their precious vote. This is the first of its kind, a truly interactive event.'

The Trial of Lord Lucan presents, for the first time, the prosecution case prepared by police for whenever he was brought to justice. It also reveals startling new details about the events leading up to the murder and the aftermath.

As prosecuting barrister Max Hardy lays out, Lucan alone was responsible for the grisly attacks on November 7, 1974. He had planned the murder down to the last detail, he says, even discussing dumping his wife's body in the Solent and bragging he would never be caught.

Mr Hardy also claims the last person to see Lucan in the hours after the attack had failed to assist police because of her 'infatuation' with the aristocrat.

For the defence, barrister Edward Henry KC urges jurors to judge the case on 'the evidence alone', saying Lord Lucan 'has been vilified… his whole life defamed in the Press'.
