Reform's chairman Zia Yusuf has resigned less than a year after taking over.

He tweeted: "11 months ago I became Chairman of Reform. I’ve worked full time as a volunteer to take the party from 14 to 30%, quadrupled its membership and delivered historic electoral results.

"I no longer believe working to get a Reform government elected is a good use of my time, and hereby resign the office."
