London - A Cross of St George-emblazoned UFO piggybacking on Comet C/1861 G1 Thatcher has been spotted grandstanding over the Thames in London.
It's the first time that the long-period comet has been seen directly above Blackfriars Bridge where 'God's Banker' Roberto Calvi RIP was found suspended 30 years ago in June this year.
Witnesses said they saw celestial hieroglyphs depicting the Order of the Garter's ancient motto Honi soit qui mal y pense ['Shame on Him Who Maligns It'] flashing from a wide portcullis.
"It means 'Don't fuck with the monarchy, Cameron'," local historian Sir Gawain Green-Knight tweeted this afternoon quoting from College of Arms-Dealing heraldic treaties.
Another translation gives 'A scoundrel, who thinks badly by it' "which brings Nick Clegg into the cowardly loop" according to Sir Gawain's warning.
This afternoon another skywatch observer noted the craft was sending a clear signal about events likely to topple the dastardly Coalition's very own Glimmer Twins this Monday, St George's Day.
"Comet Thatcher originates in the nebulous no-man's-land between the constellations Lyra 'The Liar' and Draco ' The Dragon'," Fester Red Dwarf told QM-NewsCorpse stringers.
"Ominous that it's latest appearance comes during the Chinese Year of the Water Dragon."
The chances of a 'United Kingdom Spring' coup d'etat toppling Cameron, Clegg and all the mendacious News International snoopers have increased dramatically to 2/1 according to online bookies Aintgottaprayer.con.
