Former customs officers say policing the post-Brexit border will be a mammoth task.

A Conservative MP is hoping to increase pressure on Commons Speaker John Bercow by tabling a no-confidence motion.

Mr Bercow said this week he would be "strongly opposed" to US President Donald Trump addressing Parliament, accusing him of "racism and sexism".

James Duddridge said Mr Bercow had "overstepped the mark" although he did not expect his motion to be debated.

Meanwhile an early day motion calling for officials to withhold permission for Mr Trump to address Parliament, has now been signed by 204 MPs - largely from the Labour Party.

According to the Financial Times, Rupert Murdoch was in the room when Donald Trump gave his first post-election foreign newspaper interview, to former cabinet minister and Times columnist Michael Gove.

The chairman of News Corp did not feature in photographs of the encounter last month at the top of Trump Tower in Manhattan but two people have confirmed he was in the room, the paper says.

The interview was conducted by Mr Gove, a leading proponent of the UK’s exit from the EU.

The FT says Mr Murdoch’s presence is a sign of the mogul’s interest in Mr Trump, external and his close relationship with the new president and his family.

Metropolitan Police Commissioner Sir Bernard Hogan-Howe says his officers "have just got to get on with" handling the security surrounding US President Donald Trump's state visit, despite having less notice than normal for such an event.

The trip could reportedly take place in June. 

Sir Bernard tells LBC radio that police usually got "about six months' notice" to work on such events.

He says: "At the moment, of course, people are concerned that there might be lots of protests - there have been already. 

"So no doubt as the days pass we will make assessments for what is going to happen."

Work and Pensions Committee chairman Frank Field has welcomed the Insolvency Service's decision to appoint "specialist counsel and forensic accountancy services to analyse the evidence they have gathered on the sale and collapse of BHS".

The Labour MP has been highly critical of Arcadia chairman Sir Philip Green since the group sold BHS for £1 in 2015.

He said: "It seems the net is tightening around the former directors of BHS." Mr Field added that his committee and the Forfeiture Committee - which has the power to remove honours, including knighthoods - "will await the outcome of their investigations with great interest”.

MPs voted in October that Sir Philip should lose his knighthood - but this has no legal force.

BHS collapsed with the loss of 11,000 jobs and carrying a £571m pension deficit.  

Sir Philip has vowed to sort out the pension problem.

The RMT union has announced it is to ballot members working on Arriva Rail North over strike action.

Shrewsbury's Polish-born MP Daniel Kawczynski says he is sure the rights of European citizens living in the UK will be secured during the Brexit negotiations.

He said he supported "the rights of Poles in the UK, just as I support the rights of Brits in the EU" and that he believed in the prime minister's Brexit strategy.

Mr Kawczynski also criticised an amendment put forward which called for the rights of all EU citizens in the UK to be protected.

He said it would have weakened the British hand, ahead of any negotiations.
