A crowd-funded campaign to launch a giant “Trump baby” blimp into the skies above central London during US President Donald Trump’s upcoming visit to Britain has smashed fund-raising targets.

More than $18,427 (£10,301) has been crowd-funded to get the six metre-high orange inflatable figure up in the air –smashing the original target of $9000.

The anti-Trump activists behind the campaign are determined to have their sentiments known by the President himself.

“Donald Trump is a big, angry baby with a fragile ego and tiny hands,” the crowd-funding page said.

Activists called Mr Trump a “racist demagogue who is a danger to women, immigrants and minorities, and a mortal threat to world peace”.

“Moral outrage is water off a duck’s back to Trump. But he really seems to hate it when people make fun of him,” they said.

“So when Trump visits the UK on Friday the 13th of July this year, we want to make sure he knows that all of Britain is looking down on him and laughing at him.”

However, despite the successful fund-raising, London Mayor Sadiq Khan has not given activists permission to fly the blimp as it does not qualify as a protest.

But that has not done much to deter them.

I am a giant orange baby with tiny hands. I just want to fly above Parliament on July 13th when little Donald visit Britain. But @MayorofLondon says I can’t. Sad!

More than 7000 people have signed a petition, titled Let Baby Trump Fly, calling for the blimp to be allowed to fly over Parliament Square during Mr Trump’s visit.

There is even talk of hiring a barge to “guarantee that Trump Baby will fly”.

“If we are unable to obtain consent to fly Trump Baby from Parliament Square Gardens, we may need to be creative about finding a suitable alternative location,” the protesters say.
