David Cameron has made his first foray into the crucial Rochester and Strood byelection with an appeal to voters to give him "one last go" at negotiating a better deal for Britain in Europe.
The Prime Minister - who is desperate to prevent another Conservative seat falling to Ukip's "people's army" - insisted that only he could deliver on his promised in/out referendum on membership of the EU.
With Tory MPs under instructions to make at least three campaign visits to the Kent constituency - and Cabinet ministers at least five - the Conservative high command is committed to do all it can to halt Nigel Farage's battle for the seat.
