By Christopher Lee, starring Michael York.
In November 1603 Sir Walter Ralegh was tried for treason. Was he guilty? Why was he refused a defence lawyer? Was the jury fixed? Ralegh's trial is one of the most bizarre courtroom dramas in British history.

[Picture caption] Surely one of England's most famous heroes could expect a fair trial? Not so in Sir Walter Ralegh's case it seems

The Trial of Walter Ralegh 2.15pm R4
The actor Martin Jarvis, who directed this beautifully crafted drama, described it to RT as being "wackier than Monty Python." Given that it is a representation of one of the most important trials in our history, you might find his comment little odd. But as soon as ludicrous injustice upon yet more outrageous abuse of power unfurls in the courtroom you'll see exactly what he means. Michael York, as Ralegh, milks his initially antagonistic public like a willing cow. He sports an accent not normally associated with England's most famous soldier of fortune but probably highly accurate - everything else here being so, written as it was by Christopher Lee, the man who brought us This Sceptred Isle. Unfortunately for him, the jury is in the pocket of Lord Cecil and the case for the prosecution is being delivered in supreme Satanic-style by Sir Edmund Coke (played to perfection by Ian Ogilvy - didn't he used to be the "nice one" in dramas?).
