The Daily Mail have made some very unsettling comments.
According to allegations from former Tory donor Lord Ashcroft, serialised in the Daily Mail, the PM supposedly "inserted a private part of his anatomy" into a dead pig's mouth.
Lord Ashcroft apparently cites a source who is thought to be a current or former Member of Parliament - and there are reports that photographic evidence exists also.
Naturally this has provoked quite a reaction on social media.
