Which British TV drama series do you rate as the finest of recent years?

AC-12's pursuit of bent coppers became appointment viewing, with interrogation scenes and acronyms entering everyday conversation. Few shows have united the country around a single mystery quite like 'H'.

Sarah Lancashire's Sergeant Catherine Cawood anchored one of the most emotionally rich police dramas ever made in Britain. Its Calder Valley setting felt as vital as any character.

Steven Knight's stylised gangster epic gave the Midlands a mythology of its own, complete with razor-edged caps and a thunderous soundtrack. Cillian Murphy's Tommy Shelby became an icon.

A half-hour comedy-drama that redefined what British television could do with intimacy and grief. Series two, and the Hot Priest, became a cultural moment in its own right.

A lavish, decades-spanning portrait of Elizabeth II that prompted national debate about history, memory and dramatic licence. Its production values set a new bar for British prestige TV.
