Thanks, one and all.

I blotted up the worst and then wiped down the area with dry kitchen towel. Surprisingly, this actually got rid on most of it and almost restored the surface.

I then went over the affected area with kitchen towel soaked in isopropyl alcohol and I reckon 99% of the stain has gone.

The only evidence left is where the ink had seeped into a slit in the grain and I'm going to try a few more isopropyl alcohol rubs to see if that removes the rest.
