THE pound edged higher on Tuesday as Jeremy Corbyn agreed to back a group of MPs in their attempts to halt a no-deal Brexit.

Sterling was 0.6% higher on the euro at 1.107, and jumped 0.5% versus the US dollar to 1.228.

It came after the Labour leader agreed to put a vote of no confidence in Boris Johnson on the back burner while cross-party efforts to stop the UK crashing out of the EU without a deal are prioritised.

The currency has proved to be sensitive to Brexit-related news in recent months, with standard economic news taking on secondary importance.

David Madden, market analyst at CMC Markets UK, said the pound was lifted on hopes that the MPs would be able to prevent a no-deal exit.

"While this may seem a plausible possibility, it ignores the fact that to prevent the UK leaving the EU without a deal MPs still only have one plausible option and that is to revoke article 50," he said.

"Either that or they have to hope the EU is open to extending article 50, assuming that they get asked to do so. Nonetheless the pound has continued to gain ground and is the best performing G10 currency over the course of the last five days."

The pound's rise held back top shares in London, which were flat while their European peers made gains.

The FTSE 100, which benefits from a weaker pound, was down 5.4 points, or 0.08%, to 7,089.58.

The German Dax climbed 0.62% and the French Cac was up 0.67%.

Oil prices were lower after a weekend of escalating tension between the US and China, but President Donald Trump said talks between the countries will begin "very shortly", soothing some investor fears.

A barrel of Brent Crude Oil was trading at $58.65, down 0.27%.

In London, distribution and outsourcing giant Bunzl said it was in talks with "a number of acquisition targets" as it looks to accelerate growth for the rest of 2019.

Renold, a manufacturer of industrial chains, said it had completed an investigation into misreporting of its accounts and found that the issue was confined to its Gears unit.
