A set of mutually lockable panels (1, 2), such as floor, wall or ceiling panels, comprising a first panel having a front face, a back face and an edge including a male part which is directed in a direction from its front face to its back face, a second panel having a front face, a back face and an edge including a female part for receiving the male part of the first panel in unlocked condition of the panels (1, 2), wherein the male part has an outer side which, in locked condition of the panels (1, 2), is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface, wherein the female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel, wherein the locking member has a stop surface remote from the pivot axis, which stop surface cooperates with the locking surface of the male part in locked condition of the panels (1, 2) so as to lock the panels (1, 2) with respect to each other at least in a direction substantially perpendicular to the locking surface and the stop surface, wherein at the back face of the second panel the locking member is provided with an actuator for rotating the locking member from its first position in unlocked condition of the panels (1, 2) to a second position in locked condition of the panels (1, 2) in which the locking surface and the stop surface cooperate, wherein the actuator is a protrusion, wherein the actuator is located at the locking member and has a control surface which is directed away from said back face and which is displaceable with respect to said back face in a direction from its back face to its front face so as to move the locking member, wherein the male part has a lower surface directed in a direction from the front face to the back face of the first panel and the female part has a bottom surface directed in a direction from the back face to the front face of the second panel, wherein the lower surface contacts the bottom surface in an interengaged but still unlocked condition of the panels (1, 2) in which condition the control surface protrudes from the back face, wherein the pivot axis has a substantially fixed position with respect to the second panel, wherein the locking member is formed integral with the second panel. a first panel having a front face, a back face and an edge including a male part which is directed in a direction from its front face to its back face, a second panel having a front face, a back face and an edge including a female part for receiving the male part of the first panel in unlocked condition of the panels (1, 2), wherein the male part has an outer side which, in locked condition of the panels (1, 2), is directed to the second panel in a direction substantially parallel to the front face of the first panel, and an opposite inner side which is provided with a locking surface, wherein the female part comprises a locking member, which is pivotable about a pivot axis that extends substantially parallel to the edge of the second panel, wherein the locking member has a stop surface remote from the pivot axis, which stop surface cooperates with the locking surface of the male part in locked condition of the panels (1, 2) so as to lock the panels (1, 2) with respect to each other at least in a direction substantially perpendicular to the locking surface and the stop surface, wherein at the back face of the second panel the locking member is provided with an actuator for rotating the locking member from its first position in unlocked condition of the panels (1, 2) to a second position in locked condition of the panels (1, 2) in which the locking surface and the stop surface cooperate, wherein the actuator is a protrusion, wherein the actuator is located at the locking member and has a control surface which is directed away from said back face and which is displaceable with respect to said back face in a direction from its back face to its front face so as to move the locking member, wherein the male part has a lower surface directed in a direction from the front face to the back face of the first panel and the female part has a bottom surface directed in a direction from the back face to the front face of the second panel, wherein the lower surface contacts the bottom surface in an interengaged but still unlocked condition of the panels (1, 2) in which condition the control surface protrudes from the back face, wherein the pivot axis has a substantially fixed position with respect to the second panel, wherein the locking member is formed integral with the second panel.
