Jeremy Corbyn has declared Theresa May's Brexit plans the "road to nowhere" in a fierce clash at PMQs .

The Labour leader said halfway through the government setting out Britain's future, "so far all we’ve had is waffle and empty rhetoric."

He slammed Foreign Secretary Boris Johnson for mentioning "carrots, spam, V signs, stag parties and a plague of boils" - but not Northern Ireland.

He also said the Tories want to "destroy workers' rights" and quoted a peer who said Britain “will be walking a gangplank into thin air" without a clear plan.

"Businesses need to know, people want to know, even her backbenchers are demanding to know," he added. "This government isn’t on the road to Brexit - it’s on the road to nowhere."

It comes after German Chancellor Angela Merkel apparently mocked the Prime Minister by saying she was "not frustrated, just curious" to know what Britain wants.

However, the clash at Prime Minister's Questions also came despite Mr Corbyn's own MPs pushing him to clarify his stance on Brexit - including to stay in the EU customs union.

Because of Labour's internal battle over Brexit, Mr Corbyn has rarely raised the subject in his weekly House of Commons spot.

But he devoted all six questions to it today - accusing the Tories of wanting to destroy workers' rights.

He said 62 Eurosceptic Tories - who wrote trying to force Mrs May into a Hard Brexit this week - "want a bonfire of regulations, want to destroy workers’ rights in this country."

Mrs May insisted: "I have been clear since I became Prime Minister.

It comes after Tory Brexiteers sent a leaked letter to Mrs May trying to harden the deal

"This is a government that will not only protect workers rights, but enhance workers’ rights."

But Mr Corbyn claimed Mrs May was already hardening the Brexit plans she set out a year ago.

He said a year ago, the Prime Minister declared “I want tariff-free trade with Europe”.

Now, he said, it has been “downgraded” to “as tariff-free as possible”.

"Why then did [the Brexit Department's] analysis state there could be opportunities for Britain in deregulating areas such as environment and employment law?" he said.

Mr Corbyn mocked Brexit Secretary David Davis' claim that Britain would not descend into a "Mad Max-style" dystopia.

"Doesn’t the Prime Minister feel he could set the bar just a little bit higher?" Mr Corbyn said.

Mr Corbyn stifled a theatrical yawn as Mrs May make a joke about 'Czech spy' claims

But Mrs May hit back: "The Labour Party's front bench can’t even agree with themselves what their policy is."

And she rounded off with a joke about claims the Labour leader knowingly met a Czech Cold War spy - allegations Mr Corbyn has branded "smears".

Mrs May said the UK was "unconditionally committed to the safety and security" of Europe.

"Can I suggest to him that he needs to think very carefully about the security partnership we want with the EU when we have left," she said.

"Normally he stands up every week and asks me to sign a blank cheque - and I know he likes Czechs..."

Mr Corbyn, who attacked newspapers over the claims yesterday saying "change is coming", pretended to stifle a yawn.

It came as a Tory Brexit minister today insisted there WILL be a fixed end date for the post-Brexit transition period.

Steve Baker made the insistence despite critics highlighting a leaked Government document which suggests it could last "indefinitely".

Pro-EU Labour MP Chuka Umunna said the document obtained by Bloomberg represented the "final nail in the coffin of the idea that Brexit means 'taking back control"' as the UK does not set out an end date.

The Government is aiming for a transition period of "around two years" after leaving the EU on March 29 2019, during which Britain would continue following EU rules.

The Government has previously stated that the period should be "strictly time-limited" but an end date is not proposed in the document.

Instead it points to a desire to "discuss with the EU the assessment that supports its proposed end date" of December 31 2020.

And it says the length "should be determined simply by how long it will take to prepare and implement the new processes and new systems that will underpin the future partnership", which "points to a period of around two years".

Mr Baker insisted: "What will be the case is, when we've agreed, there will be a fixed date."
