Come down to national statistics agency and spin mistruth (6)
I believe the answer is:
abseil
'come down' is the definition.
(I've seen this before)
'national statistics agency and spin mistruth' is the wordplay.
'national statistics agency' becomes 'abs' (I can't explain this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'spin' shows that the letters should be reversed in order.
'mistruth' becomes 'lie' (I've seen this before).
'lie' in reverse letter order is 'eil'.
'abs'+'eil'='ABSEIL'
'to' acts as a link.
Can you help me to learn more?
(Other definitions for abseil that I've seen before include "Descend using running rope" , "going down" , "come down quickly" , "Descend vertically by rope" , "Descend down vertical surface using rope" .)
