Justin King, the chief executive of Sainsbury's, was the star performer on Thursday evening's edition of Question Time on BBC One – even when the inevitable question aboutrunaway executive pay came up.

Despite Coalition tensions, there's still no sign of discord between the Cleggerons. Sam Cameron and Miriam Clegg made a convincing show of sisterhood after No 10's International Women's Day reception on Tuesday. The pair were later spotted together in the stalls at Wyndham's Theatre for a performance of Clybourne Park, named Best New Play at this week's Olivier Awards. Both, I'm told, laughed heartily at the show's most risqué (and least sisterly) joke: "Why is a white woman like a tampon?" asks one character. I'll let you Google the punchline.

Veteran broadcaster David Dimbleby has been honoured with a lifetime achievement award from the Royal Television Society, as he marks 50 years since starting at the BBC.

For a major corporate move that is supposed to take place before the end of this year, the transfer of 2,500 BBC staff from London to the new media centre at Salford Quays seems to be causing as many problems as it was designed to solve.

David Dimbleby has threatened to resign as chairman of Question Time in a dispute over plans to move production to Glasgow.

It was always going to be a tough midweek fixture for Clarke Carlisle, the first active professional footballer to appear on Question Time (BBC1, Thursday). He may have been playing on home turf in Burnley but the gaffer had been tinkering with the formation of the NHS front line and the opposition were deploying very defensive tactics at the Chilcot Inquiry; then shortly before kick-off, one of the star players had to stand down after lurid allegations about his private life were revealed.

Clarke Carlisle is to appear on the BBC's Question Time.

"The great thing about playing this festival is that there's music to fill any awkward silences," says Shappi Khorsandi of the jazz pleasantly leaking from an adjacent tented venue. Khorsandi, however, is not one for leaving silences; she's ever effervescent and with all the more reason to be these days, thanks to a growing audience, in part swelled by TV appearances that range from Friday Night with Jonathan Ross to Question Time.

It was one of the most controversial programmes in television history. When Nick Griffin, leader of the British National Party, was invited on to BBC 1's Question Time, it sparked massive protests. The programme, earlier this year, had extra edge because Mr Griffin was next to the black academic and playwright Bonnie Greer.
