According to The Speccie it happened thus

Unlike the Liberal Democrats’ launch this morning, Ukip did take plenty of questions from the media — including from the Telegraph’s Christopher Hope. He asked why there was only one black face in the manifesto and the room exploded with boos and cheers — egged on by party staffers —  until a group of black and Asian supporters stood up and the jeers turned into applause.

In actual fact it appears to me from the Speccie vidclip that Hope’s question was initially greeted with groans rather than boos…

However Kirkup hinted that poor Christopher might have been traumatised by the negative reaction. After all he is a Lobby Correspondent so much more familiar with the carefully choreographed world of the Westminster political village – and he does have an extremely “stressful” – lol – life (as you can see from his rather pooterish contribution to this brief report about The Lobby)

Well, if he is traumatised then it serves him right. It wasn’t a genuine information seeking question – it was a snide little piece of stirring that actually backfired as black and Asian kippers stood up to show their contempt.

Hope and his Telegraph colleagues have spent three years pouring scorn on UKIP and denigrating the party’s membership and supporters. There has been little (if any) attempt to make any serious analysis of why UKIP has grown. Instead kippers have been characterised as cartoon freaks.

What makes the whole affair even more laughable is that you would have to dig very deep into the online Telegraph to find a staffer with a black face. But Mr Hope, who is, we are informed, so knowledgeable about politics, didn’t know that Steven Woolfe, MEP, whose photo adorns the immigration section of the manifesto, is mixed race.

Perhaps he ought to get out of Westminster a little more often…
