Streamed Irish broadcaster tucking into potato (7)

I believe the answer is:

spurted

'streamed' is the definition.
(both can mean gushed out)

'irish broadcaster tucking into potato' is the wordplay.
'irish broadcaster' becomes 'RTE' (national broadcaster of Ireland).
'tucking into' indicates putting letters inside.
'potato' becomes 'spud' (synonyms).
'rte' put inside 'spud' is 'SPURTED'.
