The Conservative party has recently had ­problems with questions being asked about the authenticity of it’s campaign, following accusations airbrushing David Cameron’s campaign posters, and distorting crime statistics, and now more questions are being asked over the identities of the students who were photographed listening to Cameron’s speech at the ­University of East London on Monday.

The group of about eight young people who sat behind the Tory leader and listened quietly as he spoke of “rebuilding trust in politics” looked like students, but according to the ­president of the university’s union, they were not ­students, but young ­members of Cameron’s campaign team.

Joseph Bitrus, is reported in the Guardian to have said:

“They are not our students”

“Afterwards I spoke with one of them, and he said he had just joined the campaign a week ago and was learning how it worked.”

Bitrus said that staff and students from the University of East London had asked him who the people behind Cameron were.

“They asked because they didn’t recognise them, and they didn’t represent the multiculturalism of the university,”

Mr Bitrus said students were also disappointed that they did not get the chance to ask Cameron any questions.

Last night the Conservatives denied they had positioned young activists behind Cameron.

In 2005, Labour was accused of using a sympathetic crowd to shield Tony Blair from hostile voters, when it was noticed that the same family had been photographed in the background of two different policy launches.
