Liberal has useful information showing support (6)

I believe the answer is:

lintel

I'm a little stuck... Click here to teach me more about this clue!

'support' is the definition.
(lintel is a kind of support)

'liberal has useful information' is the wordplay.
'liberal' becomes 'l' (abbreviation).
'has' says to put letters next to each other.
'useful information' becomes 'intel' (I've seen this before. I am not sure about the 'useful' bit.).
'l'+'intel'='LINTEL'

'showing' acts as a link.

Can you help me to learn more?

(Other definitions for lintel that I've seen before include "Supporting member" , "It's found above the door" , "Supporting beam over a doorway" , "Horizontal timber support" , "support is needed" .)

I've seen this clue in The Guardian.
