Benedict Cumberbatch has joined a list of celebrities to condemn the Conservative party for planning to scrap the Human Rights Act.
The Conservatives want to replace the human rights act with a British bill of human rights, to give the government more powers against foreign criminals.
Under current legislation, the government is often unable to deport terrorists or foreign criminals, and the party therefore wants to strip them of some of their human rights.
The key change is that the Conservatives want to make all judgements in the European courts advisory rather than binding on the UK, as is currently the case.
This is seen by many in Europe as a 'red line', which could lead to Britain withdrawing from the European Convention on Human Rights.
