They tried to find a way out of the Brexit disarray... But last-ditch cross-party talks between Britain's Prime Minister and the opposition leader have failed.

In a letter to the prime minister, Labour's Jeremy Corbyn said he felt discussions had "gone as far as they can".

Insisting May's government had become unstable - its authority eroded - and undermining confidence in the "government's ability to deliver any compromise agreement".

The news came just hours after Theresa May revealed on Thursday she'll set out a timeline for her departure in early June.

The PM says she'll go after a fourth and final attempt to push her Brexit deal through parliament.

May has promised to step down after it is approved by lawmakers.

But many in her party want her to quit if the deal is rejected again.

Others want her out immediately.

May and Labour leader Jeremy Corbyn will now move to a second phase, an earlier BBC report said, aimed at agreeing on a process for parliamentary votes to find a consensus.

Waiting in the wings - hardline Brexiteer Boris Johnson announced his plans to make a bid for the leadership when May goes.

Whoever replaces her will automatically become prime minister.

And take over the reigns of the Brexit process.

Nearly three years after the United Kingdom unexpectedly voted to divorce the EU, it is still unclear how, when or if it will ever actually quit the bloc it joined in 1973.
