I don't have a proper time for this, because I got interrupted half-way through, but I spent a total of about 15 minutes on it. This included a few minutes at the end puzzling over 6dn, until I realised that my hastily bunged-in DISECT at 6ac didn't work.
Not really much to say about this: it's pretty standard fare, with a smattering of unfamiliar words but nothing that should cause undue problems.
| Across |
| 1 | One endless complaint about lacklustre inspiration |
AFFLATUS - FLAT contained in A FUSs. I thought this rather obscure word must have come up before, because I solved the clue almost immediately, but I can't find any evidence that it has. I wonder how I knew it. |
| 6 | Cut out organ part and remove piano from consideration |
RESECT - RESpECT. |
| 9 | What we all pass by beginning to rile aristocrat |
PEER - PEE ('what we all pass', tee hee), Rile. Of course PEERs aren't necessarily, or indeed mostly, aristos these days, but a seat in the House of Lords still costs quite a lot of money. |
| 10 | Russian leader’s edict is classified |
| PUT IN ORDER - or PUTIN ORDER. 'Invade Crimea', for instance, or 'give me that steel company'. |
| 11 | Call in at once to order shelving |
| CANCELLATION - (CALLINATONCE). 'Shelving' doesn't really mean CANCELLATION, but it's close enough I suppose. |
| 14 | Polish annoyed when one of two Poles arrested? Partly |
| YES AND NO - (ANNOYED)* containing S for south. 'Polish' is the (slightly strange) anagrind. |
| 15 | Well and good, I’ll indicate your seat at the match |
| GUSHER - G, USHER. |
| 16 | Tons in bags? |
| STACKS - S(T)ACKS. &Lit. |
| 18 | Calming influence finally found in second case |
SEDATIVE - influencE contained in S, DATIVE. |
| 20 | Political grouping dismayed a pal terribly |
| LIBERAL PARTY - (APALTERRIBLY)*. Another rather strange anagrind: 'dismayed'. |
| 22 | Old Queen and English authoress made a little contribution |
| DID ONES BIT - Queen DIDO, then NESBIT, author of The Railway Children, many other books for children and some for adults. |
| 24 | Daughter separated from cruel guy gets a good guy |
HERO - HEROd. |
| 25 | Goes hungry retaining little energy? These should help! |
| FEASTS - F(E)ASTS. |
| 26 | Green minerals (type finally clear in Chambers) |
PERIDOTS - P(typE, RID)OTS. Appropriately Chambers has 'chamberpot' for 'chamber'. I had heard of these stones, but had no idea they were green. |
| Down |
| 2 | Ten working in awful serfage? These aren’t! |
| FREE AGENTS - an anagram of TEN contained in an anagram of SERFAGE. |
| 3 | Treasury minister in cricket ground with top Government members |
| LORD CHANCELLORS - Put George Osborne in St John's Wood and you get Chris Grayling. Or Thomas (Cardinal) Wolsey and Thomas More, during the reign of Damian Lewis. |
| 4 | Ousted Head quietly went first |
| TOPPLED - TOP, P, LED. Not sure why there's a capital H in 'Head'. |
| 5 | Rested for a day |
| SAT - DD. |
| 6 | Norway replaces Italy, messing up administration |
| RUNNING - N (Norway) replaces the I (Italy) in RUINING. |
| 7 | Married musicians with limitations |
| STRINGS ATTACHED |
| 8 | School managed without parking |
CO-ED - COpED |
| 12 | Person who’s bashed our ears? |
| AROUSER - (AROUSER)*. A kind of semi-&Lit, I think. I suppose if someone bashed your ears it would, er, wake you up. |
| 13 | Don’t sustain grassland and ban bull |
| LEAVE TO ROT - LEA, VETO, ROT. |
| 17 | Parts of a larger group fixed loans externally |
| SUBSETS - SUB(SET)S. |
| 19 | Blood pressure drug, mostly slow to act |
DILATOR - DILATORy. |
| 21 | Assistant’s suggested course of action: the last shall be first |
| AIDE - IDEA with the last letter moved to the beginning. |
| 23 | Roll in bed alongside partner, at first |
| BAP - first letters of bed alongside partner. |
