Two "must be" answers but cannot see why. 23 across - RETIE. 17 down - SEA GREEN. Two unsolved items. 8 down (8). -L-A-D-R. Hero`s declaration to partner Bush. 25 down (5). L-A-O. Pick up pound on merit.
Many thanks, dannyk13, hartox and dtcrosswordfan. All your answers make perfect sense when I see them but I would not have solved them in a month of Sundays!
