    Abstract: A pitch controlled wind turbine (1) comprising a tower (2), a nacelle (3) mounted on the tower (2), a hub (4) mounted rotatably on the nacelle (3), and at least three wind turbine blades (5) is disclosed. Each wind turbine blade (5) extends between a root end (10) connected to the hub (4) via a pitch mechanism, and a tip end. The wind turbine (1) further comprises at least three blade connecting members (6), each blade connecting member (6) extending between a connection point (7) on one wind turbine blade (5) and a connection point (7) on a neighbouring wind turbine blade (5), the connection points (7) being arranged at a distance from the root end (10) and at a distance from the tip end of the wind turbine blade (5). The wind turbine (1) further comprises at least three pre-tension members (8), each pre-tension member (8) being connected to one of the blade connecting members (6) and to a hub part (4, 9, 26), the pre-tension members (8) thereby providing pre-tension in the blade connecting members (6).
