Republic has welcomed the Supreme Court decision in the Guardian’s fight for release of prince Charles's letters.

The group has now called for the law to change so future requests for disclosure can be successful. Any new request will have no chance of success at the moment because in 2010 the government changed FOI laws to remove the public interest test.

Republic CEO Graham Smith said today:

"This is excellent news. The government must now act to end royal secrecy. Any risk to the monarchy must pale against a risk to democracy from having an activist prince acting in secret."

"We can't have a situation where we don't know what influence Charles is having on government policy."

"The changes made to FOI laws in 2010 must be reversed so future requests for disclosure can be successful."
