Messagespace, the political advertising network co-founded by Guido Fawkes editor Paul Staines, will no longer run ad sales for politics titles Conservative Home and Labour List.

From July, advertising on the two sites will be handled by Total Politics Group, the Lord Ashcroft-owned company that publishes titles including The House, Politics Home and Conservative Home itself.

Total Politics said the deal “advances Total Politics Group’s position as the largest, most diverse and best-connected political advertising platform in the UK”.
