Pointless giant Richard Osman tears himself away from his desk by Alexander Armstrong's side to slide into one of the guest seats for the first of a new series of the topical news quiz. Osman is surely destined for the guest host gig at some point but tonight it's down to Stephen Mangan to give Ian Hislop and Paul Merton free rein to roam around the lunatic fringes of the news, while Osman's fellow guest, Joan Bakewell, offers sage titbits.

The satrical edge on HIGNFY has dulled very slightly over the years. These days, Ian Hislop and Paul Merton don't so much lacerate the week's events and personalities as chew them over with the odd comic flight of fancy.

Occasionally, let's be honest, that makes for an underwhelming episode, where the panellists never get up a head of steam and only the host's scripted gags keep things rolling. But more often, the big old beast of a show rouses itself and delivers an enjoyably surreal spin on the news, providing us with a neat comedy coda to the week. One of the best episodes of the last series had Richard Osman as a guest, punning about David Cameron's "mandate" on gay marriage and showing an almost shameful knowledge of Spice Girls hits. Happily, he's back again tonight, with the excellent Stephen Mangan in the host's chair for the first show of series (drumroll, please...) 45.

Whan an omnishambles: Ian Hislop on state of the media

We first met Private Eye editor Ian Hislop in 2008 when we went round to his office and drank tea and bitched about the state of British media. Looking back at the last decade of British journalism seemed like the kind of thing we should do on our anniversary, so we called on Hislop again.

Inside the private world of Ian Hislop

Ian Hislop has been puncturing egos in Private Eye and on Have I Got News For You for quarter of a century. How does he fare when the focus is on him?

Youth and experience on Have I Got News for You this week. Wet-behind-the-ears comedian Jack Whitehallp.o[ takes the presenter's chair, while "Bletchley Park Baroness" Trumpington is, at 90, the programme's oldest ever guest. But Ian Hislop and Paul Merton must be careful how they handle her. When Lord King of Bridgwater dared to suggest, in a House of Lords speech, that Baroness T looked old, she promptly gave him two fingers. Lord Sugar's wry sidekick, Nick Hewer, completes the line-up.

Angus who? Tonight marks 10 years since the job of host was given over to a succession of guest presenters following the Deayton sacking. The vast majority of the temporary emcees have excelled in the hot seat, thanks largely to a sharp presenter's script and Paul Merton and Ian Hislop keeping the conversation fizzing. Tonight, Homeland actor Damian Lewis takes the chair for the fifth time as UKIP's Nigel Farage and The Simpsons' Harry Shearer join the panel.

It's back and Friday nights make sense again. Nothing starts the weekend in quite the same way as this half-hour dollop of headline-based sarcasm, joyful meanness and unashamed unpleasantness. It's the best way to unpack the accumulated stresses of a working week. Some of the guests might occasionally be dull, like those terrified politicians who try too, too hard to be funny, but what the heck, team captains Paul Merton and Ian Hislop have seen it all before and the pace never flags.

Making her debut as host is Clare Balding, newly anointed National Treasure after stints commentating on the Olympics and the Paralympics won her a devoted following.

Private Eye hit its highest circulation for more than 25 years as it turned 50 - and its editor has never had a higher public profie.

Why British satire is hard bloody work

Peter Cook's old Establishment club is back in London after 50 years - will it bring some Armando Iannucci- or Ian Hislop-esque hard satire to the live circuit?

Susan Calman happy to be same-sex marriage role model

Susan Calman can cope with the rapier wit of Paul Merton and Ian Hislop on Have I Got News For You. She can hold her own with Stephen Fry on brainbox show QI [on later in the year].

But the Glasgow comic has no answer for the homophobic abuse she has experienced in her home town.
