Since November 2015, Leicester Against War / Leicester For Peace has been staging a weekly protest asking Britain to stop military intervention in Syria.
The protest takes place from 5.30pm to 6.30pm at the Clock Tower every Friday and is the longest running current protest of it type in Britain.
This week's protest will feature a performance from Leicester's leading street choir, the Red Leicester Choir which is also calling for an end to British military intervention in Syria.
