You are right, this is a male palmate newt. The scientific name has now changed to Lissotriton helveticus. If you add an ID to update this I will agree it.
On another note, it is interesting to see it in breeding "dress" at this time of year. It in not unknown for newts to breed in the autumn in mild years, particularly in the south and west.
Thanks for the update on the scientific name!
