Guido Fawkes, (the top UK political blog, for the benefit of non-UK readers) is reporting that BBC political teams have been told not to go away over the weekend, this warning representing a red-alert for a potential general election announcement.
I think I'm right in saying that if an election is indeed called, Parliament will be dissolved and the CRU hearings will not take place.
Richard Drake in the comments notes that yesterday, after taking evidence from Sir John Beddington, Select Committee chairman Phil Willis bid the scientist "farewell" in the following terms:
This is likely, Professor Beddington, to be the last time we have the pleasure of you before our Committee. Could we thank you very strongly indeed for all the work you have done with our Committee and indeed your predecessors.
Given that Sir John is due to appear in front of the committee on Monday to give evidence on the CRU affair, it does rather look as if our suspicions may be correct.
