Thanks to newly revealed documents, we learn it was a deliberate act to make the country more multi-cultural (and thus more likely to vote Labour).
Platell complaining about immigrants coming here to affect the outcome of elections? Seems odd, given she's an immigrant from Australia who was an advisor to William Hague and worked to get the Conservatives elected in 2001.
But you don't really go to Platell for common sense or intellectual rigour.
And this week, she surpassed herself:
A survey purports to show that many more people would vote in a General Election if they could do so on Twitter. In a civilised democracy, the idiots who use Twitter should be banned from voting altogether.
Yes, because everyone knows that the mark of civilised democracies is that they arbitrarily ban thousands of people from voting for no reason whatsoever.
How much do the Mail fork out for such dim, juvenile observations?
Previously, she had dismissed Twitter as:
the domain of the inane, the insane and the desperate.
Platell - like all Mail columnists - has to be a professional hater. Everything's crap, everyone needs to be criticised, nothing is ever any good.
Particularly Twitter, because a) it's modern; and b) it was all nasty about Jan Moir boo hoo hoo.
Never mind that the Mail constantly uses Twitter for celebrity gossip and other stories.
Never mind that people such as Oscar-nominated Thick of It creator Armando Iannucci uses Twitter. Let's not celebrate his achievements. Let's call him an insane idiot who should be disenfranchised instead.
Still, good job the newspaper Platell writes her drivel for is above all this Twitter nonsense.
And to see exactly how much they hate it, go to their Twitter feed at @mailonline.
