Progressive Labour Party adopted candidates Leroy Bean and John Gibbons face a fight to hang onto their status after the party threw the door open for them to be challenged.It's understood Tourism Minister Patrice Minors could move from Smith's North where she's considered likely to lose to Opposition Senate leader Michael Dunkley to the East End constituency where Pastor Bean was rolled out ten months ago. Pastor Bean and Mr Gibbons won at local elections in St George's South and St George's West last August and were the PLP's only two adopted candidates ahead of the next general election.However, it's believed high-ranking party members have pointed to constituency boundary changes since then, meaning primaries will take place in those two constituencies along with the other 34 branches across the Island.Pastor Bean, who was selected and then de-selected in favour of former Attorney General Phil Perinchief before the 2007 General Election, is said to have recruited many people to his branch in recent months, with some party members arguing he and Mr Gibbons should be allowed to keep their positions as they were elected under the PLP's constitution.Mrs Minors, who is very close to Premier Paula Cox and has become a key member of her Cabinet, defeated Senator Dunkley in Constituency ten in one of the 2007 General Election's defining moments.But the boundary changes mean that constituency now contains many more white and likely One Bermuda Alliance voters, tipping the balance heavily in Sen Dunkley's favour.Mrs Minors lives in the East End and some say a switch to a St George's seat may be the only way she can retain her place in the House of Assembly; she has already been polled in the area.Meanwhile, the PLP's central committee is due to discuss proposed constitutional changes giving the party leader more authority in candidate selection next Monday.At least 60 people are said to have applied for candidacy, including an usually large number of white people and conservative black people.Each must now go through an approval process, before primaries are staged at branch level over a six-week period.Several sitting MPs are under threat, with a host of newcomers looking to take advantage of constitutional changes making the application process more democratic.Public Information Minister Neletha Butterfield is said to be challenged by at least three people in Pembroke West Central; National Security Minister Wayne Perinchief is facing challenges from at least three, including former Senator Walton Brown, in Pembroke Central; Junior Economy Minister Ashfield DeVent is being targeted by Government consultant Rolfe Commissiong in Pembroke South East.A three-way battle is thought to be shaping up in Southampton East, where former Senate leader David Burch has declared an interest in the seat currently held by Speaker Stanley Lowe. Health Minister Zane DeSilva, whose grip on Southampton East Central has been loosened by boundary changes, has told colleagues he's interested in switching to the safer Southampton East seat.Former United Bermuda Party leader Wayne Furbert is the overwhelming favourite in Hamilton West due to his large family backing, despite challenges from his cousin Senator LaVerne Furbert and former treasurer Charles Clarke.New member Darius Tucker, the former UBP MP, has a decent chance in Hamilton South, but that seat is widely expected to go back to the Opposition at the next election anyway.The Listers' dominance in Sandys could be coming to an end, with Walter Lister having already confirmed his retirement and party insiders noting Dennis Lister's prolonged spell on the backbench. Senate leader Kim Wilson and party organiser Makai Dickerson have both previously indicated their interest in West End seats.Backbencher Dale Butler yesterday confirmed he's staying in Warwick North East despite an influx of likely OBA voters due to boundary changes; Senator Jonathan Smith is likely to run in the Smith's area while Senator David Burt is considered extremely likely to run.Pastor Bean and Mr Gibbons could not be reached while the PLP said in a statement yesterday: “We will not comment on candidate selection as it is an internal matter for the party.”Useful website: www.plp.bm.
