Sorry - I'm a week behind and haven't any letters!
47a - Political statement included by spokesman if 'e's Tory (9)
52a - Islander and I at sea repeatedly on short journey (11)
54a - One side ahead of the other shortly before close of play, as it should be (7)
55a - Two turns, one incomplete? That's true (6)
Should get [even] me started - thanks!
