In previous years the school have published free open lectures in MP3 format, i have found them to be of use but i believe the link has now be taken down for those. On this youtube channel they have posted some lectures which maybe of use to law students on the London LLB International programme. I've just taken a brief look at one of manslaughter by gross negligence by Robert Smith QC and it looks of really good use to those studying Criminal Law.
This channel is one to look out on as to what will be posted up for future reference.
A link can be found here.
