I understand there is a debate going on within government about the availability of interpreters to people taking the UK driving test who cannot speak English.

I am at a total loss to understand why there is any need for debate.  If anyone is to be allowed the privilege of driving on English roads, surely it is a sine qua non that they should speak English well enough to take part in the UK driving test?  The UK government is apparently concerned that an interpreter might answer questions for the candidate and which they cannot answer for themselves.

Well, what nonsense. Surely, the important test is whether or not anyone can make themselves understood in the English language?   If they can’t and won’t, they have no place in an English country and certainly not driving on English roads.
