Canvassing, either in person or by telephone, lies at the heart of grassroots politics. To win, you have to learn voters concerns, identify those voters who are likely to support you, and remind them to turn out and vote.

On Tuesday 22 November, with the Sleaford and North Hykeham by-election coming up, CMF Deputy Chairman was doing his bit at the Conservative Campaign Headquarters call centre.

As you can see below, also canvassing were the Defence Secretary the Rt Hon Sir Michael Fallon MP and the Lord Chancellor and Secretary of State for Justice Rt Hon Liz Truss MP.
