Since Boris Johnson became Prime Minister, the Conservatives have gained 10 points to stand at 30%, a survey by Deltapoll showed.

Meanwhile a Sunday Times also reported a spike for Boris, with the Tories jumping 6pts to 31%, Labour 10 points behind on 21%, the Lib Dems on 20% and the Brexit Party falling to 13%.

"And today I am going to deliver on my commitment to that vision with a pledge to fund the Leeds to Manchester route.
"It will be up to local people and us to come to an agreement on the exact proposal they want – but I have tasked officials to accelerate their work on these plans so that we are ready to do a deal in the autuRead More – Source
