The world is mourning a superstar, declares the Daily Mirror - one of many papers to change its front page after the death of George Michael was announced late last night.

The Sun speaks of a sense of shock at the death of a pop icon. The Times says 2016 has claimed another of the world's most cherished artists - a multi-tasker, who was composer, singer, producer and occasional instrumentalist.

But the paper says his drug problems meant he had a difficult relationship with the press - it emerged last year that he had spent some time in rehab, fighting an addiction to crack cocaine.

The Guardian reports that councils have been given permission to carry out more than 55,000 days of covert surveillance over five years - including spying on people walking dogs, feeding pigeons and fly-tipping.

The paper says a mass Freedom of Information request by the Liberal Democrats found that 186 local authorities had used the Regulation of Investigatory Powers Act to gather evidence via secret listening devices, cameras and private detectives.

A number of councils stressed that they sought permission for many more days than they actually used. But the paper says critics are pointing to claims that the powers would only be used when absolutely necessary to protect people from extreme threats.

The Daily Mail says undercover and armed police will be protecting Boxing day shoppers - with forces across the country on high alert for a possible terrorist attack. The paper also says concrete barriers are expected to be used to protect people seeing in the New Year in Trafalgar Square. The Mail says the measures follow an urgent review of security after the attack on a Christmas market in Berlin.

The Guardian suggests that the Queen's Christmas Day address contained what could be seen as a coded message to the nation in the aftermath of the Brexit vote.

The paper highlights a section of the broadcast in which the Queen said people facing a challenge sometimes talked about taking a deep breath, to find courage and strength.

There are the customary photographs of the Royal Family at Sandringham, where they attended the Christmas Day church service - though without the Queen, who's been suffering from a heavy cold.

But several front pages prefer pictures of Prince George and Princess Charlotte clutching pieces of striped candy as they left a service in Berkshire with their parents. The Mail says they stole the show.

The Telegraph reports that nearly a thousand precious items in national museums and galleries have been damaged over the past decade. The paper says a string of incidents included staff tripping over in the dark and children putting sticky fingers on canvases. And a ration book on display at the Imperial War Museum in London was damaged by a leak from a corroded tin of soup.
