Rigged Audiences?

The Question Time panel in Boston.

Highly-respected political commentator, Trevor Kavanagh of The Sun, has suggested the BBC may have rigged its audience for Question Time in Boston last week to produce a more pro-immigration slant to the questions and comments.
While conceding that UKIP Leader Nigel Farage can look after himself, Kavanagh slated Tory defence minister Anna Soubry for her anti-UKIP rant, peppered with inaccuracies, and wrote: "But what was even more startling that Soubry's tirade was the seemingly co-ordinated barrage of criticism he [Nigel Farage] faced from the Bostonians themselves.
He went on to comment: "The audience was stacked with questioners who appeared suspiciously well-rehearsed, self-confident and bullishly determined to be heard."
Kavanagh referred to UKIP's tremendous result in the May local elections – grabbing nine out of the 11 council seats representing Boston – as a major coup and evidence of public alarm over immigration in the area which has seen the town's population increase by 20,000 in ten years, putting pressure on schools, health and social services.
