Nope i dont think there are any either,Our UK TV now is mostly Ads on Insurance/claims,Reality TV and general crap that nobody wants to watch.
We do get a show on Channel 5 called "The Gadget Show" which reviews and tests gadgets and sometimes they have the occasional game on there but thats about it. :/
I have seen the gadget show a few times, also watch top gear, just thought you guys would have had a gaming show as well, since we have one in Australia.
We used to have one on Sky1 a few years back now called Gamezville, which was about upcoming and current games, and there is a channel, which I unfortunately can't find now, which broadcasts league gaming, usually late at night
