Manchester United v Liverpool postponed after fans invade Old Trafford in protest

• Two police officers injured in ugly clashes
• Thousands of supporters gather outside Old Trafford

Manchester United's game with Liverpool at Old Trafford on Sunday was postponed after a planned peaceful protest outside the stadium by fans angry with the club's owners, the Glazers, spilled into chaotic and violent scenes as a group of about 100 broke into the ground, causing criminal damage and forcing some staff to lock themselves into rooms for safety.

The postponement of the Premier League match between the two most storied clubs in English football to an as yet undetermined date was confirmed almost five hours after supporters gathered at the stadium. It adds further uncertainty to United's fixture list in a week when they are due to play the second leg of their Europa League semi-final with Roma, and is the most graphic illustration yet of the breakdown of trust between fans and owners.
