The Labour MP Mary Creagh criticised the appointment on Twitter, while Paul Flynn, another Labour MP, said he was pleased about the news because it would discredit the honours system, which he has long opposed."
It not only discredits the honours system but the role of British royals who are taken along for the ride. The Queen will be expected to approve Crosby's knighthood but will she be inwardly applauding the man?
That is one question.
The Queen at least on the surface tries to stay out of politics unlike her meddling sons and grandson, Prince Charles and Prince William.
But the reality is that the Queen meets with the PM of the day on a regular basis in one-to-one conferences.
A Spectator blog puts a very different and right-wing perspective on the affair with this "Was a political knighthood ever more deserved than Lynton Crosby’s? His personal involvement was the difference between defeat and victory – he kept Ed Miliband out of No10. As Tim Montgomerie observed earlier, a hereditary peerage would be in order for that alone."
But that is just one more reason why he should not be dubbed Sir Lynton even with a barge-pole.
His knighthood discredits a wobbly system, plays party politics and is a disgrace.
It undermines the huge numbers of voters who did not fall for Crosby's, or Rupert Murdoch's, spin and sleazy politics.
They are two Australians who played a huge part in undermining the opposition in the UK and ensuring the Tories got the key to Number 10 for five more years.
Crosby, the so-called Wizard of Oz, is all that is wrong with politics.
He works for the piper who pays the price albeit preferably the right-wig piper.
He worked on Tony Abbott's 2013 election campaign in Australia and helped turn it around but when Stephen Harper's campaign in Canada 2015 began to flag he jumped ship.
Yes a man with plenty of money but a shortage of principles.
A man worthy of a knighthood?
Yes if like this writer you believe the honour's system stinks from top to bottom and should be scrapped.
