Good morning. It’s Chris Johnston getting you started today with all the latest from the campaign trail – as well as what’s ahead. You can follow the rest of the day’s politics on our live blog.

What’s happening?

Labour says it will scrap the Brexit white paper and replace it with new negotiating priorities with the emphasis on keeping the benefits of the single market and customs union. In a speech on Tuesday Keir Starmer, the shadow Brexit secretary, will set out the plans alongside a pledge to unilaterally guarantee existing rights for all EU nationals as part of the party’s election manifesto, hastily being put together following the snap election announcement last week.

Voters are being urged to unseat prominent Brexit-supporting MPs such as Iain Duncan Smith, Theresa Villiers and Kate Hoey by the successor organisation to Britain’s pro-EU remain campaign. Open Britain has drawn up an “attack list” of 20 seats, held mostly by Conservative MPs, where constituents voted to stay in the EU but their representatives are Brexit supporters.

Tony Blair argues that Labour’s only chance lies in convincing voters that it will hold the government to account on any deal with the EU.

Meanwhile it’s not been a great start to the week for Ukip as speculation mounts that the party leader, Paul Nuttall, will not stand and other high-profile names including Arron Banks and Suzanne Evans declined to fight for seats.

At a glance:

Poll position

An ITV/YouGov poll puts the Tories on 40% support in Wales, with Labour on 30%. That would see the Conservatives win 10 seats from Labour to put them on 21 versus 15.

Make no mistake, replacing the Labour leader now would terrify the Tories.”

English voters admire Nicola Sturgeon – but they fear her too, writes Deborah Mattinson of research consultancy BritainThinks for the Guardian.

One voter told us: “I thought she was going to be Salmond’s puppet, but she’s turned out to be really strong and tough. It’s hard not to admire her, but I like her too.”
