'in the london area you can get to the' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'match by motorway' is the wordplay.
I cannot quite see how this works, but
an anagram of 'match' is 'tcham' which is within the answer.
'motorway' could be 'mi' (resembles M1, English motorway) and 'mi' is present in the answer.
No letters remain.
This explanation may well be incorrect...
