Update 1939: I now learn that political reporters from the Tory-backing papers were called in one by one to discuss how Team Cameron would deal with "Cleggmania" and to be offered Tory HQ's favourite titbits about the Lib Dems - much of which appears in today's papers.

The key personal allegation about payments from donors into Nick Clegg's personal
bank account came, however, from the Telegraph's expenses files. Incidentally, the party has now published details of Nick Clegg's bank statements and party accounts showing that Mr Clegg received payments totalling £19,690 from three businessmen (Neil Sherlock, Michael Young, Ian Wright) and then paid staff costs of £20,437.30 out of the same account. According to these figures, Mr Clegg actually paid £747.30 out of his own money towards staff costs.
