BBC News - Cynon Valley MP Ann Clwyd should face re-selection, Labour says 4 November 2014 Last updated at 17:17 Labour leaders have confirmed that Cynon Valley MP Ann Clwyd should face re-selection after reconsidering her decision to step down at the election. The 77-year-old MP announced in February she would retire after more than 30 years in Parliament but said in September she had changed her mind. Welsh Labour said the selection of a candidate for 2015 had already begun. Labour's national executive committee decided on Tuesday to press ahead with the process. Shortlist row Ms Clwyd said in September that local voters had asked her to reconsider her retirement, and said she had received a "very enthusiastic" reaction to her change of heart. Trigger ballot Under Labour party rules a serving MP can be re-selected by a "trigger ballot" if more than 50% of local party members agree to back them. However, sources within the Labour party questioned whether there was sufficient time to organise a trigger ballot in Cynon Valley before the 2015 general election in May. Labour's national executive committee decided on Tuesday to ratify a sub-committee's decision to press ahead with a full candidate selection process.
