A new political party inspired by the success of French President Emmanuel Macron has embarked on a national campaign to overturn the Brexit vote.

The Renew party has vowed to be the “more military arm” of the Remain campaign, with plans to field more than 200 candidates at the next general election, to ramp up pressure on Brexiteer MPs in pro-EU constituencies.

Inspired by the rise of President Macron’s populist movement En Marche!, the centrist party said it could appeal to voters who felt “politically homeless and abandoned” by the EU referendum result and disillusioned by mainstream parties.

Speaking at a launch event in London, James Clarke, one of the party’s leaders, said: “Some of the anti-Brexit pressure groups and movements are very much focused on asking people to pressure their local MP to have a second thought on Brexit.

“What we are is almost the more military arm of that movement, whereas we are actually standing candidates in seats to threaten those MPs that are not changing their minds, or are not standing up for the views of their constituents.”

Renew has recruited more than 1,000 supporters and received 450 applications from budding MPs, with plans to recruit candidates to stand in each of the 650 parliamentary constituencies.

The party will face its first test in the local elections in May and has launched a crowd-funding campaign to ensure it can field some candidates in time.

Sandra Khadhouri, another party leader, who worked at the UN and Nato, said “extremes are prevailing” in the wake of the referendum vote and compared Britain to a conflict zone.

She said: “Millions in this country feel politically homeless right now and abandoned. Brexiteers and Remainers, old and young, north and south. Many are disappointed with the false promise of Brexit.

“It is leaving us poorer, damaging us in many ways, and distracting us from addressing real problems of inequality and division.

“Existing parties are failing to protect people’s interests due to personal ambition and tribal loyalties. Extremes are prevailing.”

The biggest issues facing UK on leaving EU Show all 8 1 /8 The biggest issues facing UK on leaving EU The biggest issues facing UK on leaving EU Post-Brexit immigration workers sorting radishes on a production line at a farm in Norfolk. One possible post-Brexit immigration scheme could struggle to channel workers towards less attractive roles - while another may heighten the risk of labour exploitation, a new report warns. PA The biggest issues facing UK on leaving EU Customs union A key point in the negotiations remains Britain's access to, or withdrawal from, the EU customs union. Since the referendum there has been hot debate over the meaning of Brexit: would it entail a full withdrawal from the existing agreement, known as hard Brexit, or the soft version in which we would remain part of a common customs area for most goods, as Turkey does? No 10 has so far insisted that “Brexit means Brexit” and that Britain will be leaving the customs union, but may be inclined to change its position once the potential risks to the UK’s economic outlook become clearer. Alamy The biggest issues facing UK on leaving EU Northern Ireland-Irish border Though progress was made last year, there has still been no solid agreement on whether there should be a hard border between Northern Ireland and the Republic of Ireland. To ensure borderless travel on the island, the countries must be in regulatory alignment and therefore adhere to the same rules as the customs union. In December, the Conservative Party’s coalition partners, the DUP, refused a draft agreement that would place the UK/EU border in the Irish Sea due to its potential to undermine the union. May has promised that would not be the case and has suggested that a “specific solution” would need to be found. Getty The biggest issues facing UK on leaving EU Transition period Despite protests from a small number of Conservative MPs, the Government and the EU are largely in agreement that a transitional period is needed after Brexit. The talks, however, have reached an impasse. Though May has agreed that the UK will continue to contribute to the EU budget until 2021, the PM wants to be able to select which laws made during this time the UK will have to adhere to. Chief negotiator Michel Barnier has said the UK must adopt all of the laws passed during the transition, without any input from British ministers or MEPs.

May insists that those who arrive during the transition period should not be allowed to stay, whereas the EU believe the cut-off point should be later.

Infighting within the Cabinet has prevented a solid position from being reached, with some MPs content that "no deal is better than a bad deal" while others rally behind single market access. The EU has already confirmed that access to the single market would be impossible without the UK remaining in the customs union.

However the UK cannot make trade agreements with another country while it is still a member of the EU, and the potential loss of trade with the world's major powers is a source of anxiety for the PM. The EU has said the UK cannot secure trade deals during the transition period.

The EU has refused to give British banks passporting rights to trade within the EU, dashing hopes of a special City deal. However according to new reports Germany has suggested allowing trade on the condition that the UK continues paying into the EU budget even after the transition period. Getty

Ms Khadhouri said the message to wavering Brexit voters was ”it’s not your fault” – as many had not been given enough information on the reality of leaving the bloc.

It comes as Theresa May gears up for a crunch Cabinet meeting this week, where senior minister will head to Chequers to thrash out what Britain’s future relationship with the EU should be.
