Grant Holt (sounds like halt)?

Yes . Another ex Forest man who improves once he leaves the City ground

Yes, not good enough for us apparently such was our embarrassment of riches up front. And now we can barely buy a goal

A little bottle, reportedly (boxer)

Amir Khan? (A mere can)

Spot on

Non-consonants also, we hear.
(Golf)

Hmm..., I just wonder if this is a Korean lady golfer we've not heard of....Val Tu or something like that....

I was thinking Korea or Japan as well. Isoa Aolki sounds like his name consists of vowels , but the Ki bit rather spoils that theory. Are we on the right track?

Yes, you're on the right track but not Korean or Japanese.

....Taiwanese.

Ay-Yu Tu

Yes, correct.

A Ford , perhaps , surrounded by bombs in the country.

Athletics

( 6,7) Won a medal at last year's WC, and competed at Glasgow at the weekend.

Hannah England. ?

A feline with an "R" on a scottish island, supermarket singularly. She's a tryer.

Athlete,

Just to explain. Ford is Anna, bombs are H bombs and the country is self explanatory.

very clever

( 8, 8 )

Thought the first name must start Cat.... obviously but not so sure now that it's eight letters, can't make Cathleen work

R can mean King / Queen cryptically (Latin Rex / Regina), don't know if that's relevant

Scottish isle... Lots of them obviously, maybe Lewis, Mull, Skye

Supermarket singularly = S?

She's a tryer might be an 'overall' clue

Catriona Morrison

Well done

feline = Cat

"R"

Scotish Isle= Iona

Supermarket = Morrisons ....singular Morrison.

Multiple Ironman and Triathlete winner at world level,
Yet another of the UK's unsung woman champions in world sport.

I would never have got Catriona Morrison as been the answer!.....lol

Well done indeed!!!!

Is JBO doing a new clue?

Bump potato and cuppa, we hear
