The Observer's Andrew Rawnsley reviews the Westminster headlines of the week, with his own Magnificent Seven, as European issues and the advice from leaders' parents on the NHS dominated the headlines.

The Scissor Sisters singer Ana Matronic, who backs the Democrat Party, looks at the "inflammatory" comments of Donald Trump, who may win the Republican nomination for the election later this year.

She spoke to Andrew Neil, David Lammy and Michael Portillo on This Week, about the likely winner in the presidential contest.

Suzanne Evans is asked why she lost her role as UKIP's co-deputy chairman, after she and Neil Hamilton were replaced in their roles.

When asked by Andrew Neil about Nigel Farage, she said: "I don't think I have done anything to upset him."

And in the This Week interview, she was asked whether her party leader or Boris Johnson would be the best person to lead the Leave campaign in the EU referendum.

More than half of Scottish small businesses do not feel well informed about the EU referendum, a survey finds

Chancellor George Osborne tells the BBC an EU exit would cause a profound economic shock, as ex-Tory leader Lord Howard backs the Out campaign.

Question Time continues on BBC One, and right afterwards Andrew Neil and co will be here with This Week. You can watch it all on the live coverage tab above.

On Friday George Osborne's trade visit to China gets under way, as does the Spring conference season - with the Green Party first up.

We may also hear more about former Tory leader Michael Howard's decision to back the Leave campaign in the EU referendum.

Earlier today:

• New migration figures sparked a row between the two sides in the EU debate
• Labour leader Jeremy Corbyn said he would keep police and crime commissioners in place as he launched his party's campaign for May's elections, and:
• The government cancelled a contract to develop a GPS tracking system for offenders after spending £21m on the project

Nick Ferrari claims the mayor of London has "expressed a well-articulated and genuine view" on the EU.

The LBC radio host looks at the claims that Boris Johnson's backing for leaving the EU was a "cynical bid to gain the keys to number 10."

But in a personal film over a round of wiff waff, he said the MP plays an open handed game "and that may just deliver him the prime ministership as well as Brexit".

Speaking on Question Time tonight, Downton Abbey creator and Conservative peer Julian Fellowes said he'd like the UK to leave the EU.

He said it was "nonsense" and "complete fantasy" that German car makers or French wine producers would "turn their back on one of their best markets".

Although he loved being European, he said leaving the EU would mean Britain would have "unfettered access to other world markets" and  "we won't have to live under rules we haven't asked for or voted for."

Lord Fellowes said immigration was not one of the reasons he wanted to leave the EU. He said although the UK needed a better balance with immigration, the UK should "never want to shut our doors completely" and "why shouldn't they (immigrants) want a better life?"

Shadow international development secretary Diane Abbott says she is glad an EU referendum is taking place - she hopes it will be "a referendum for the people" and not be based on "games" within the Conservative Party. The UK does not have an "open door" immigration system, she adds.

Free movement goes "hand in hand" with the single market, says Environment Secretary Liz Truss. "There's no utopia where we can simply close the borders and say our economy will remain intact," she adds.

The first question asks whether we have to leave the EU to get control of immigration.

Here's what the Local Government Association says about the increase in rough sleeping in England that was revealed earlier:

The long awaited childhood obesity strategy will not now be published before the summer, the Department of Health has confirmed.

It means a row about a possible new sugar tax has almost certainly been delayed until after the referendum.

A Department of Health spokesman said: "The childhood obesity strategy will be a key step forward in helping our children live healthier lives.

"There is still work across government to be done to get it right, so we are now confirming that the strategy will be published in the summer."

The EU referendum campaign has been in the spotlight again, after a row between the leave and remain campaigns over the latest immigration statistics.

Net migration to the UK - the difference between the number of people leaving and arriving - stands at 323,000, with 172,000 migrants arriving from Europe last year.

David Cameron said the figure was "still too high" but insisted his EU reform deal would help to cut immigration to the UK. But senior Conservatives including employment minister Priti Patel said the only way to control immigration was by leaving the EU

In other developments:

• David Cameron said "jobs would be at risk" if the UK left the EU, in a speech at BAE systems in Lancashire
• Jeremy Corbyn has pledged Labour would retain the posts of police and crime commissioners and make them "more accountable"
• The number of people sleeping rough in England increased by 30% in a year, new figures show
• There have been sharp increases in the number of new homes being started and finished in England compared with a year ago, according to new figures
• Scottish MP Natalie McGarry has been briefly detained by security forces in Turkey
• Communications watchdog Ofcom has said BT must open up its cable network and allow competition to improve UK internet connections

The government has cancelled a contract to develop a GPS tracking system for offenders after spending £21m on the project.

Ministers ordered the bespoke system with Worcestershire-based Steatite in 2014 after security firms G4S and Serco were investigated for overcharging.

However, "significant problems" with the programme were identified last year the Ministry of Justice (MoJ) said.

Steatite, based in Redditch, is yet to comment.

Andrew Bingham calls the Mottram-Tintwistle bypass, which has been put forward as a solution to traffic problems in the area, "almost as fabled as the Loch Ness monster".

"Governments of all colours have promise to deliver it and have failed," he says.

He calls on the government to "give us some hope that this process can be conducted with urgency" in the reply to the debate.

Conservative MP Andrew Bingham tells MPs he "can't begin to express the sense of frustration that's felt by my constituents" caused by congestion on the roads around Glossop and High Peak.

He tells MPs that the normally bad traffic was made "even worse" when one of the two roads through Glossop - which links the East Midlands with Manchester and the North East - was closed due to a burst water main. 

The results, he says, were "catastrophic" and nearly led to a fatality when a child, who had suffered a seizure, experienced an "unacceptable delay because of blocked roads".
