Lord Ashcroft just sent a potentially very rude tweet about the prime minister

Lord Ashcroft is still not very happy about the exchange rate on his £8m donations to the conservative party it seems.

The former donor was the one who released thatunauthorised biography of the prime minister.

Ashcroft wrote in the preface to the book that after David Cameron became PM in 2010, he was offered the job of junior Foreign Office whip:

After putting my neck on the line for nearly 10 years - both as party treasurer under William Hague and as deputy chairman - and after ploughing some £8m into the party, I regarded this as a declinable offer.

He has subsequently said that the book was:

Not about settling scores.

However, following Iain Duncan Smith's resignation (which some commentators have called a political move against the decidedly pro-EU Cameron and Osborne camp) Ashcroft appears to have spiced up his Tweets a little with some more anti-Cam venom.

For instance, can you see the message in this cryptic tweet?

Or the reason behind tweeting the odds for who will become the next prime minister?

It seems like the #IDSofMarch is an apt hashtag for the events of the last 24 hours.
