A Labour AM who criticised the Welsh government spending nearly £20m on M4 relief road plans has been sacked as a committee chair by the first minister.

Jenny Rathbone said an "unhealthy culture" at the top of the government stopped AMs from speaking out.

Last week, she said she was "appalled" by the money was being spent preparing for the proposed road around Newport.

On Tuesday, she said Carwyn Jones had dismissed her as chair of the committee overseeing use of EU funds in Wales.

Here's the full story.

The government's Immigration Bill has cleared its first parliamentary hurdle, despite opposition from Labour, Lib Dem and SNP MPs.

MPs voted to give the bill a second reading by a margin of 49, after Labour's bid to block it was rejected by 40 votes.

The bill aims to tackle illegal immigration. It proposes a new offence of illegal working and requires landlords to carry out checks on prospective tenants.

The plans now face detailed committee-stage scrutiny from MPs.

A round-up of the political development this Tuesday:

• John McDonnell has defended his budget surplus rule U-turn following a backlash from some Labour MPs - saying he had changed parliamentary tactics - not economic policy
• The  government announces it has withdrawn from a controversial £5.9m prisons deal with Saudi Arabia
• Home Secretary Theresa May says tackling illegal immigration will mean "greater fairness to British citizens and legitimate migrants", as she opened a debate on the Immigration Bill
• UK inflation has turned negative again, falling to -0.1% in September
• Deputy Labour leader Tom Watson has been invited to appear before the Home Affairs Committee over his pursuit of sex abuse allegations against the late Lord Brittan.

The chairman of the Lloyds Banking Group says he doesn't think Britain can stay in an unreformed European Union.

Lord Blackwell, a Conservative, stressed he was speaking in a personal capacity. Taking part in a debate in the House of Lords on the European Union Referendum Bill, he said:

He went on to say: "Nor do I believe that there is a compelling economic argument to override those considerations".  

During the Home Affairs Committee's hearing on the migrant crisis earlier, minister Richard Harrington refused to say how many Syrian refugees had arrived in the UK under the government's expanded resettlement scheme. He said he wouldn't provide "a running commentary". Read our full story here. 

Yvette Cooper, chair of Labour's refugee taskforce and former home secretary, said it was "totally unacceptable" and called on the government to "come clean" with the figures.

As peers start debating the legislation paving the way for an in-out referendum on the UK's membership of the EU...

Veteran Labour MP Dennis Skinner has been accused of making a sexist remark at a government minister.

The MP for Bolsover was rebuked by Business Minister Anna Soubry after they clashed during a Commons debate on the steel industry.

He appeared to say "You even look like Thatcher" - a reference to Britain's first woman Prime Minister Margaret Thatcher.

The MP for Broxtowe said she was offended at what she felt was a sexist remark, adding: "You should know better."

The UK is set to have a referendum by the end of 2017 on whether or not to remain a member of the European Union.

Both "in" and "out" campaigns have launched. But how well-informed are people on the basics of the EU?

A recent poll from YouGov , externalfound that 16% of people in the UK are undecided on how they will vote.

There's a clearly a desire to know more, as Newsnight, external finds out.

Labour deputy leader Tom Watson has been invited to give evidence to the Commons Home Affairs Committee over his pursuit of sex abuse allegations against former Conservative Home Secretary Leon Brittan.

Yesterday, Mr Watson refused to apologise for demanding that police investigate sex abuse claims against the late peer.

The committee's evidence session on the investigation into Lord Brittain, will take place on 21 October.

Chris Grayling said he didn't believe the proposals, which give English MPs an effective veto at certain stages of a bill, were "controversial or problematic" and said they would not place the Commons Speaker in an "invidious" position.

He told MPs that "all" English colleagues supported the plan - although during earlier Commons debates some English Conservatives were among those to speak out against the proposals, before Mr Grayling said they would be redrafted.

The minister told the committee his plan "is a better way than seeing two thirds of Scottish MPs lose their seats".

The leader of the Commons, Chris Grayling, will set out further details to MPs on Thursday about his proposals on English votes for English laws. 

Mr Grayling told the Scottish Affairs Committee today that the plans were a "sensible balance" to give England more say in its own affairs.

There's cross party opposition to his plan to amend standing orders to limit the rights of Scottish, Welsh and Northern Irish MPs at certain stages in the passage of a bill on issues deemed England-only by the Speaker.

BBC political correspondent Vicki Young says shadow chancellor John McDonnell's U-turn on the budget surplus rules has caused a lot of upset within the Labour Party.

Interestingly, she says, most Labour MPs agree with the position he has ended up in, but they are "very upset" at the way the decision was reached, fearing it confuses people and damages the party's economic credibility.

Some more from the Home Affairs Committee. Chairman Keith Vaz asks whether individuals who have offered their own houses to re-home refugees - including high profile MPs such as Nick Clegg and Yvette Cooper - will be utilised by the government.

Minister Richard Harrington says the government aims to make use of "all the people who have contacted us"  but adds that it "doesn't think people staying in their homes is the best way to deal with them" due to the refugees specific needs.

Labour MP and committee member David Winnick quips there's plenty of space into Chequers,the prime minister's country residence.
