Newsjack is a topical sketch show from BBC Radio 7, then BBC Radio 4 Extra. The show aims to get comic mileage from the news - political, cultural, sports, and trivia. Originally hosted by Miles Jupp, now hosted by Justin Edwards, the tone is lively, satirical, and distinctly irreverent.

Many of the sketches are written by members of the public, as the programme is happy to accept unsolicited material.

Regular strands currently include:

The Newsjack App: Newsjack has moved into the 21st Century and finally got its own "app". Well, actually, it's just the answerphone of a Nokia 3310. But like the "Vox Pops" of previous series, this is the perfect place to air your one-liners or quick jokes. They can be about any prominent news issue and these messages will then be heard throughout the show.

LooseJack: LooseJack is Newsjack's sister magazine show, featuring a panel of out-spoken journalists and celebrities. If you want a loud and poorly-formed judgment on the latest news, then you've come to the right place. Whether it's opinionated harridan Carol EggmcMuffin mouthing off about the differences between men and women or cheeky chappy Joe Thwash being cheeky and a chappy, LooseJack is the number one forum for discussing the week's big stories.

Things We've Learned This Week: This is a chance for those submitting jokes to the show to boil down the week's news into three easy lessons.

From the Archive: We delve through the archives to discover how topical events were covered back in the day.

Newsjack Films: Since the British Film Council has gone up the spout, Newsjack has bravely stepped in and started producing topical films.

Corrections: An old "favourite" and another good opportunity for short jokes. At the end of the show these 'corrections' pretend to address any mistakes made in last week's show.

"And finally...": A post-credits sequence where the show pretends the current episode is an old show and make jokes about how the world might have changed since the programme went out.

Our Review: This show has made a positive impression on us. Each week, some skits fall flat, but there's also always at least a couple of gems in each episode to keep us entertained.

Newsjack should certainly be praised for giving new writers a chance to get their sketches broadcast. Quite a number of aspiring writers have managed to get material on the show over the last few series.
