You'll need a DPDT relay with a 230volt coil. Easiest to obtain would be
an octal type from the likes of TLC or Maplin.

You strap NO the first pole to NC of the second. And NC of the first pole
to NO of the second.

The switch lines of the two way circuit (usually marked L1 & L2 on a two
way switch) go (in) to the C and (out) from NO and NO (Or NC and NC)
