Actress Pamela Anderson signed the letter with her love for "sexy" WikiLeaks founder Julian Assange.

Actress Pamela Anderson has called for Julian Assange's release in a love letter to the WikiLeaks founder.

While gushing over Assange's "sexy bravery and courage" in the letter titled Why My Heart Stands with Julian, she also brands UK leader Theresa May "the worst prime minister in living memory".

Assange shouldn't remain "trapped in a small room" in the Ecuadorian Embassy in London now Sweden has dropped its sexual assault case against him, Anderson says.

"Theresa May, who is on her last legs. Theresa May of the pyhrric victory [sic].

"Theresa May, who won't shake the hand of the victims of the Grenfell fire. Who doesn't care about poor people. Who doesn't care about justice or peace. Who doesn't care about Julian.

"The worst prime minister in living memory."

In the note, published on published on the former Baywatch star's website and shared by WikiLeaks, Anderson addresses world leaders, including French President Emmanuel Macron, asking them to step in and grant Assange asylum.
