WikiLeaks founder Julian Assange has condemned what he called the “terrible injustice” of the years he has spent in prison and inside the Ecuadorian embassy in London after an investigation into allegations he committed sex crimes was dropped.

Appearing on the balconyof the Ecuadorian embassy in London where he has been in self-imposed for over four and a half years under threat of extradition, Mr Assange said: “Today is an important victory, but it by no means erases seven years of detention without charge under house arrest and almost five years in this embassy without sunlight.

Seven years without charge while my children grew up without me.

This is not something that I can forgive. It is not something that I can forget.

The inevitable enquiry into what has occurred in this moment of terrible injustice is something that I hope will be more than just about me and this situation because the reality is detention and extradition without charge has become a feature of the European Union, a feature that has been exploited in my case for political reasons.

Sweden’s chief prosecutor announced earlier today the investigation into accusations of rape against Mr Assange would not be pursued.

The Australian is still wanted for questioning in the US in relation to the work of Wikileaks.

The Metropolitan Police released a statementconfirming there is still a warrant out for hisarrest for failing to appear in court in June 2012.

When asked about the possibility of legal action against Mr Assange, Prime Minister Theresa May said that it was a matter for the police.
