Almost half of British voters would prefer the country to leave the European Union without a Brexit deal and Labour’s Jeremy Corbyn not to become prime minister, according to a YouGov poll.

When asked to choose between that scenario and one in which Corbyn becomes the country’s next leader and holds a second referendum on Brexit, just over a third backed the option that could see Britain remain in the EU.

Nearly one in five people said they remain undecided.

The poll represents a setback for Corbyn's plan to create a cross-party coalition to fight the government's plan to leave the EU with or without a deal on October 31.

The Labour leader is trying to convince others to call a no-confidence vote in Boris Johnson, the country's current prime minister, and install Corbyn as the U.K.'s interim leader until a new general election can be called.

Corbyn on Saturday reiterated his intention to lead a caretaker government if Johnson is ousted. “I am the leader of the Labour Party, Labour is the largest opposition party by far. That is the process that must be followed,” he told ITV News.

“We will do everything we can to stop a no-deal Brexit,” Corbyn added, stating: “What we need is a government that is prepared to negotiate with the European Union so we don’t have a crash-out on the 31st [October].”

According to the YouGov poll, Brits are still against a no-deal Brexit, with 49 percent agreeing that would be an unacceptable final outcome, versus 38 percent of respondents that found it acceptable.

More people polled were in favor of accepting the deal negotiated with the EU than were against.

The YouGov poll also suggested Brexit-supporting voters are more united than those who would prefer the U.K. to remain in the 28-country bloc.

Four out of five Brexit supporters told the polling company they would support a no-deal Brexit with Corbyn not becoming the next prime minister, while only 64 percent of voters who want to remain in the EU want the Labour leader to take over as prime minister and call a second Brexit referendum.

Almost a quarter of those who voted to remain in the EU during the 2016 referendum would prefer to see the U.K. leave the bloc instead of Corbyn taking over as the country's next leader, according to YouGov.

The poll of 1,968 people was conducted on Thursday and Friday.
