David Cameron's constituency office calls out police to deal with the Bishop of Oxford

From the Independent:

David Cameron’s constituency office has come under fire for calling the police on the Bishop of Oxford and Reverend Hebden as they attempted to present him with an open letter on food poverty. 

Their letter, part of the End Hunger Fast campaign, was signed by 42 Anglican bishops and more than 600 clerics and called on the three party leaders to work with the parliamentary inquiry into food poverty to implement its recommendations. 

However, despite David Cameron’s Witney office expecting their visit, they were barred from presenting the letter and instead greeted by three police officers.

I guess this 'Christian country' thing must be a work in progress.
