Open in relation to king’s programme (4,4)
I believe the answer is:
star trek
'programme' is the definition.
I know nothing about this answer so I can't judge whether this works.
'open in relation to king's' is the wordplay.
'open' becomes 'start' (I've seen this in another clue).
'in relation to' becomes 're' (regarding).
'king' becomes 'K' (abbreviation for king in chess).
'start'+'re'+'k'='STAR TREK'
Can you help me to learn more?
(Other definitions for star trek that I've seen before include "Kirk, Spock et al on TV" , "Extraterrestrial journey" , "Science fiction series" , "Enterprise?" , "TV series" .)
