A latch and lock assembly (10) for a double door arrangement having a first door and a second door, in use, being pivotally mounted for movement about either a common pivot axis or closely adjacent parallel pivot axis to a door frame, the latch and lock assembly (10) being selectively operable to hold the first door to the second door in a connected mode for connected pivotal movement or to release said first and said second doors from said connected mode whereby said first and said second doors are capable of independent pivotal movement, said latch and lock assembly (10) further enabling at least one of said first or said second doors to be releasably latched to or latched and locked to said door frame, the latch and lock assembly (10) including: a releasably latching mechanism operatively adapted to releasably latch at least one of said first and said second doors to the door frame; a releasable connection mechanism operatively adapted to releasably connect the first door to the second door; and an operating system operatively adapted to control both the latching mechanism and the connection mechanism, said operating system including an electrical drive means (208) operable by an electric power source (209) to drive actuating means operating at least one of said releasable latching mechanism or said releasable connection means. - - - C ---------------- - - -- . . . .. ... -- -- --- --- (NN
