I doubt if Plaid will introduce an all women shortlist for the constituency, and local branches can be fiercely independent, so I wouldn't go as far as to say that a female candidate for the seat will be inevitable, but there will definitely be pressure from certain influential quarters of the party for the successor to be a woman.
But who are the likely candidates?
From a national perspective one would have to pick Gwenllian Lansdown as a potentially good MP, but she has no local connections. 12 months ago Siân Caiach might have been a name to listen out for. Two other possibilities are the AM's Bethan Jenkins and Nerys

Does any reader have any local insight?
The other question being raised since Adam's announcement is where he will stand in 2011? Given the tight timetable involved in his academic sabbatical to Harvard, the answer might be nowhere. Indeed he might be wise to see how the dust settles in Wales after a Conservative Westminster victory and hold off re-entering the electoral fray until 2015.
Correction I apologies to Nerys Evans AM for mixing her name up with that of the Rhyl superstar and brilliant actress Nerys Hughes. I'm sure that both would make exceptional MPs.
