'puts pressure on thanks to politicians' is the definition.
I can't judge whether this definition defines the answer.

'on thanks to politicians' is the wordplay.
'on' says to put letters next to each other.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'to politicians' becomes 'mps' (I've seen this in other clues).
'ta' put next to 'mps' is 'TAMPS'.
