Boastful types with Lord Melvyn introducing creative activities (9)

I believe the answer is:

braggarts

'boastful types' is the definition.
(people who brag)

'lord melvyn introducing creative activities' is the wordplay.
'lord melvyn' becomes 'Bragg' (broadcaster Lord Melvyn Bragg).
'introducing' says to put letters next to each other (some letters go before others).
'creative activities' becomes 'arts' (I've seen this before).
'bragg'+'arts'='BRAGGARTS'

'with' acts as a link.

I've seen this clue in The Telegraph.
