All juries are instructed by the presiding judge to try and reach a unanimous verdict.
However, in criminal cases, after a jury has deliberated for at least four hours and have not reached a unanimous verdict the judge may instruct them to consider a majority verdict.
A majority verdict is a verdict agreed to by all except one juror and can only occur if the foreperson states in open court there is no probability of the jury reaching a unanimous verdict, the Juries Act stipulates.
If a majority verdict can not be reached, a judge can also give what is known to lawyers as the Papadopoulos direction.
A Papadopoulos direction encourages jurors to persevere with their deliberations and to demonstrate a willingness, having listened carefully to the views of other jurors, to change their view.

However, Singh's defence lawyer, Marie Dyhrberg QC, argues the 28-year-old had been publicly and falsely accused and "is living every man's worst nightmare".
