Feeling of pressure prime minister's limited? (4)
I believe the answer is:
heat
'feeling of pressure' is the definition.
'heat' can be an answer for 'pressure' (I've seen this in another clue). I am not sure about the 'feeling of' bit.
'prime minister's limited?' is the wordplay.
'prime minister' becomes 'heath' (Edward Heath).
'limited?' means to remove the last letter (I've seen 'limited' mean this).
'heath' with its last letter removed is 'HEAT'.
Can you help me to learn more?
(Other definitions for heat that I've seen before include "Energy that causes a rise in temperature" , "Warmth - gossip mag" , "High temperature" , "Apply warmth" , "Warmth - passion" .)
