It's December 1981 and Kenneth Kendall, Michael Buerk and Brian Hanrahan bring us news of martial law in Poland and the big freeze in the UK. We've edited out the filmed inserts to just leave the studio material (with the exception of some shots of "Britain's newest commuter train fleet", which 30 years later is still running on the same lines).
