Help appreciated with the exact parsing for these....
14a. King, a tyrant, with no love for student (7) - LEARNER (Student)
16a. Winemaker's pet drink in Champagne? (7) - CHATEAU
25d. Notice youngster's lifting cloth (7) - BUCKRAM (Cloth) - I thought 'Youngster' could be 'BUCK', but that leaves 'RAM' for 'Notice' so I'm not sure.
