Hello rintin, thank you for your question and subsequesnt clarification.
The television special you are thinking of is called "Sleepers" and
was first aired in the UK on BBC2 in 1991. I have searched high and
low but unfortunately it seems that it is not available on DVD, Video
or any other kind of format. Even the BBC online store does not list
it http://www.bbcshop.com/icat/2 and it is not listed on ebay either
in the UK or USA. One day it will turn up, but until then we will have
to wait.
"ONLINE EPISODE GUIDE" "Sleepers BBC 1991"
http://www.action-tv.org.uk/guides/sleepers.htm
"In 1966, a mission was inaugurated by an official named Zorin where
two KGB agents were to be placed in Britain as normal British
citizens, one in the industrial north and the other in the commercial
south, but due to circumstances they have been forgotten about for the
last 25 years. In that time, the agents have changed a lot and are now
as British as the British themselves; one is now living as Albert
Robinson, a Union official at a factory in Eccles, happily married
with three children, the other is now Jeremy Coward, a high flying
yuppie in the financial world in London.
When one of Albert's children accidentally activates his long
forgotten radio in his attic, Albert hears a Russian voice calling
him. This is a moment that is to change the lives of Albert and his
family for some time. Panicked by this communication, Albert makes
contact with Jeremy, who is somewhat surprised to hear from him. They
arrange to meet. In Moscow, the KGB decide that it is time to bring in
these sleeping agents, and Major Nina Grishina flies to London, to
join the local KGB agents in trying to find them. The arrival of a top
ranking official intrigues both CIA and MI5"

"Sleepers (8/91)
A comedy/drama about two KGB agents (Nigel Havers, Warren Clarke) sent
deep undercover to Britain in 1966 and are all but forgotten 25 years
later. Now the agents are more British than the British, and the KGB
not to mention the CIA and MI5 want to know what happened to them.
Produced by Verity Lambert, watch for an inside joke: When the
Russians discover the secret training center underneath the Kremlin
used in 1966, the television is playing Adam Adamant Lives, the first
series she produced after Dr Who"

counter-plots as the two lost agents, now utterly assimilated, try to
avoid detection."
