Newspapers rush to be first, don't check properly and often get things wrong. They'll often refuse to admit a mistake, particularly if it's an embarassing one or they are worried about libel damages.
Politicians also lie often whenever their lips move but it is usually opinions about their policies, i.e. merely conning the British public
An MP who factually lies to damage another politician is potentially in a lot of trouble.
Carmichael is in even more trouble:
. His lie cost £1.4 million
. He involved a foreign ambassador & consul. France are miffed. If they were a hostile country, the consequences could have been very serious
. This type of leak may break the Official Secrets Act
The SNP reported him to the parliamentary commissioner for standards, Kathryn Hudson. Likely next steps:
. She is expected to find that there is reason to investigate and then she will submit her findings to the parliamentary committee on standards, which has the power to recommend sanctions, including the suspension of an MP.
. The recommendation is then voted on by MPs on the floor of the Commons.
. MPs will probably vote to suspend Carmichael for 10 days or more
. This would then automatically trigger a new process under the Recall of MPs Act (which the Liberals were responsible for introducing !):
. If at least 10% of Carmichael’s constituents sign a petition calling for a byelection, then one must be held. A local newspaper there has been running a poll and 95+% want him to go.
btw, I want Scotland to stay in the UK, but there has been so much neglect and stupidity over the years, that I think they'll gradually move out
