Cameron "determined" to win back seat; we speak to Andrew Bridgen and Transport Secretary Patrick McLoughlin - and hear from our political editor Nick Robinson.

As Emily Thornberry apologises for her Rochester tweet, Harriet Harman tells us Labour are "One Nation" party. Lib Dem president Tim Farron says supporters in Rochester voted tactically.
