ACROSS
1 NEW (STATE)SMAN – I was trying to justify The Spectator, as I have at least read that rag occasionally…
9 COSA NOSTRA – anagram* of CARTOONS AS
10 DEER – reed reversed for the female deer.
11 PAN+THE+ON
12 AFRESH = REF HAS*.
13 FIAT – double definition.
15 TRANSITORY – TORY around RAN + SIT.
17 RAPPORTEUR – RAP + PORT + RUE reversed.
19 SALE – hidden.
20 NOW NOW – NOW (Present) x 2; I suppose the idea of the parental bit is that a mother or father is more likely than any other group to use these words of mild rebuke.
22 UNCLE SAM – CALUMN[i]ES*; a metonymous usage.
24 BLUR – literal is ‘to fade’ and the wordplay a reversal of RU[n] and LB.
25 STABILISE – IS A BIT LESS*; an &lit.or all-in-one.
26 PINCHPENNIES – PINCH + PENNE + S around I.
DOWN
2 EXACT – double definition.
3 STONES (as in the ageing rockers) +THROW (project).
4 ANTONIA – NATIONA[l]*; the ‘l’ (‘front in London’) needs to be deleted (scrubbed).
5 EVA – the middle letters of chEap shaVers slash give Adolf’s bit on the side.
6 MODE(RATE)S[t]
7 NEEDS – sounds like ‘kneads’.
8 MONA LISA – SOMALIAN*.
12 ABSTRACTION – AB’S + TRACTION. Easy to put ’abstracting’.
14 TIP-AND-RUN – what Jos Buttler did yesterday; a tongue-in-cheek crypticky definition referencing a variety of cricket played by children or for fun in which the batsman must run to the other end each time he faces a ball, regardless of whether he gets a clean strike on it or even hits it at all.
16 RELEASED – the RED surrounds (‘bands’) the let (or LEASE); literal ‘free’.
18 EDUCATE – E DUCE holding A+T.
21 OXLIP – X in PILO[t] reversed.
23 ELITE – reversed hiddens don’t come much easier.
25 SOH – sounds like ‘sew’. Oops, ‘sow’ – thanks, Jack
The sound-alike at 23dn should be ‘sow’ (broadcast).
