Donald Trump has suspended for an initial six months the entry of foreign students seeking to study or participate in exchange programmes at Harvard University.The US president issued the proclamation on Wednesday, citing "national security" concerns and declaring it "detrimental" to US interests to continue allowing foreign students at the institution.

Harvard has responded by calling the order "retaliatory" and emphasised it would continue to protect its international students, according to Reuters news agency.Trump's announcement is a further escalation of an ongoing legal row with one of the US's most prestigious universities after Harvard refused to yield to a series of White House demands in April.Wednesday's order comes after

(DHS) from banning international students at Harvard in a ruling last week.Trump's proclamation accused Harvard of developing "extensive entanglements" with foreign countries and continuing to "flout the civil rights of its students and faculty".

"Considering these facts, I have determined that it is necessary to restrict the entry of foreign nationals who seek to enter the United States solely or principally to participate in a course of study at Harvard University," he said.

The order also suspends visas for international students seeking exchange programmes and directs the secretary of state to consider revoking existing visas of students currently studying at the university.The care Mrs Readhead received formed part of both RCP reviews carried out on behalf of the hospital trust.

Pre-op checks had indicated Mrs Readhead's left side was to be used for the TAVI, as her right side had some blockages because of calcified arteries.The manufacturer of the TAVI device that was to be implanted had also written a technical report clearly stating that access via the patient's right artery was unsuitable.

On the day of the operation however, the TAVI medics went in through Mrs Readhead's right leg by mistake. Realising their error, they paused to consider their options but decided to continue - despite the procedure being an elective rather than an emergency operation.They attempted to deploy the TAVI three times.
