The creator of Line of Duty has suggested that this Sunday’s episode could be the final ever instalment.
Line of Duty’s fifth series comes to an end with a 90-minute episode this Sunday.
However, according to Mercurio, a sixth series hasn’t been confirmed let alone a seventh.
Fans are hopeful the identity of the enigmatic “H” will be revealed following a devastating episode that saw Superintendent Ted Hastings end up behind bars.
