When several defendants are brought to trial jointly they may take the number of peremptory challenges specified in Rule 123 collectively and each defendant may, in addition, take two (2) more peremptory challenges separately.
In that event the prosecuting attorney is also entitled to an additional number of peremptory challenges equal to the total number of additional challenges specified by this rule for all the defendants.
