I have found it challenging this week and would appreciate some help with my last three please.
43a Scot's drunk small dram and promises to pay (8)
S?o?I?u?
It looks like stotious but I have never heard of it!
36a Is seeing TV commercial the wrong way (5) d?t?s
Looks like dates.
19a Way of getting back voting system one's not imagined being without (8) ?e?r?s?l
Looks like reprisal but can't see a connection to voting system.
