Seemed extra tough today. Any ideas, please, on:
3d Transport workers let in functions in suit (11)
4d Most happy to have rich cooked dishes, being at end of diet (11)

Also, can anyone explain why 2d is Reagan and 7d Ado. (If they're right, that is)

3d businessman
4d chirpiest

2d soldiers = R.E., once more ousting current = AGA(i)N
7d old = O, bill's over = AD at first [it is a down clue]

[Lie-in King]

3d Businessman - 'sines' (functions) (in) 'busman' ("worker", singular in clue)
4d Chirpiest - anag 'rich' + 'pies' + (die)t

2d Reagan (leader) - RE (soldiers) + aga(i)n - i = symbol for electric current
7d Ado - ad (bill, poster etc) (over) o(ld)

Thank you both!
