Just a couple of quick questions, what size earthing cable needs to
be employed in earth bonding a new sink in the kitchen [...]

A kitchen sink does not need to be earth bonded unless it has a metal
waste
pipe in contact with the earth outside. However the incoming water
service
should be bonded to the main earth terminal (in or near the consumer unit)
with a minimum of 10mm^2 cable


(16mm^2 recommended)


by who? Never seen this on normal domestic wiring
