For peace of mind. The OP was troubled enough to measure and find a voltage (a minimal ghost voltage at that)
The desk has the extended socket installed so an earth is easily available. Use that and any ghost voltage will be gone and peace of mind is restored.
I'm not sure BS7671 was compiled for peace of mind.
This desk, from the description given, is not an exposed conductive part, therefore does not require 'Earthing'.
If it requires 'Bonding', would depend on whether it is an extraneous conductive part, which would require testing to which Lucien referred to in #8. Not using a voltage checker.
Bonding something, which is not an extraneous conductive part can, in certain circumstances make the situation more dangerous by distributing further any touch voltage, e.g. bonding internal metal cable tray used by MI cables.
If the advice is to bond the metal desk, then this would have to extend to any metal sinks, metal baths, metal radiators, metal windows etc. Thankfully, something resigned to the past of the 15th edition.
