'link with europe' is the definition.
I can't judge whether this definition defines the answer.

'new luncheon's lost over' is the wordplay.
'new' is an anagram indicator.
'lost' indicates named letters should be taken away.
'over' becomes 'o' (cricket abbreviation).
'luncheon' with 'o' removed is 'lunchen'.
'lunchen' anagrammed gives 'CHUNNEL'.

Can you help me to learn more?
