Prince Andrew: Queen 'not ill but not taking risk'

The Duke of York said the Queen cancelled her visit to London's Tech City today as a precaution - but she is not ill.

Prince Andrew said his mother -who has been suffering from the symptoms of gastroenteritis - felt it was "more sensible not to risk coming out at the moment ".

He told an audience at the UK's answer to America's Silicon Valley that he would encourage the Queen to come on a future occasion.

Alternatively, he joked:"We'll just have to take the whole office into the Palace which is the easiest way of doing it!"
