One Bermuda Alliance MP Mark Pettingill has handed his safe Opposition constituency to former political rival Jeff Sousa.The OBA today unveiled Mr Pettingill as its General Election candidate for Warwick North East, where he faces a likely uphill battle against long-serving Progressive Labour Party MP Dale Butler.Mr Sousa will fight in Warwick West, the area Mr Pettingill has served since the 2007 election, a traditional United Bermuda Party area expected to be one of the OBA’s strongest constituencies.The pair were UBP colleagues until Mr Pettingill quit to help form the Bermuda Democratic Alliance in 2009. Mr Sousa then became the UBP’s representative for Warwick West, clashing frequently with Mr Pettingill who was the Warwick West MP for the BDA.Both later became founding members of the OBA earlier this year.Meanwhile environmentalist Ray Charlton was unveiled as the Alliance’s candidate for Sandys North, a solid PLP seat currently held by Estates Minister Michael Scott.
