From the Witney Liberal Democrats website:
Hundreds of volunteers are flooding into the constituency this weekend to help with Liz’s campaign in the Witney by-election.
Tim Farron said: "Taking over such a large building is a real sign of our commitment to West Oxfordshire and to the strength of the campaign we are running here."
Liz Leffman said: "I have been so touched by the huge number of people who have been coming from all over the country to help. This brilliant new HQ has really put us on the map in Witney and underlines that we are the only challengers to the Conservative Brexit government in this by-election."You will find full details of how to help in the campaign on the Witney site.
