Crossword Genius

Annoyed at dirtier manoeuvre (9)

Ross

I believe the answer is:

irritated

'annoyed' is the definition.
(I know that annoyed can be written as irritated)

'at dirtier manoeuvre' is the wordplay.
'manoeuvre' is an anagram indicator.
'at'+'dirtier'='atdirtier'
'atdirtier' with letters rearranged gives 'IRRITATED'.

(Other definitions for irritated that I've seen before include "Annoyed" , "Cross" , "Irked" , "rubbed up the wrong way" , "put out" .)

I've seen this clue in The Daily Express.
