Stuck On Guardian Se Corner Again

[olegrahl]

Help with 19d appreciated. Salty islanders losing heart to Norway (7)
-R-N---. That would help with 26a (?Printing) which would help with 24d (?Loth). But wouldn't explain why 15a is agitate. But you can't have everything. Many thanks.

[bibblebub]

brinish

agitate = 'it' inside a gate'

[bibblebub]

26a: spitting = 'sting' outside 'pit'
24d: (s)loth

[olegrahl]

Thanks very much. Should have got brinish, thought the word was briney or brackish.
Don't understand why a crowd is a gate and cannot parse 11a.

[dannyk13]

A crowd at a sporting venue is called a gate.
Clue for 11a?

[olegrahl]

Runner, having consumed pork pie, first to go into spasm. 10 (Fibrillate).

[dannyk13]

Fib(pork pie -lie) + rill(runner-stream) + ate(consumed)

[legin7]

11a Fibrillate..... rill...ate...fib (first)

[olegrahl]

Thank you DannyK13 but should fib not be inside rill (having consumed) or the comma after pie eliminated so it reads pork pie first?

[dannyk13]

It does say ' pork pie first'. Setters often put commas in to confuse.
