Deputy Prime Minister Nick Clegg has wished the Duchess of Cambridge the "best of luck":
Best of luck to the Duchess of Cambridge today, as she gives birth to her second child. The thoughts of the whole country will be with her.
Nick Clegg has reacted with humour after a young man lost his trousers while trying to take a selfie with the Deputy Prime Minister.

You can watch the moment the young man lost his cool again here:
Nick Clegg's visit to Solihull College hit a bum note when a young man lost his trousers as he approached the Deputy Prime Minister for a selfie.
It was unclear whether the incident was the result of a wardrobe malfunction or a deliberate attempt to embarrass the Liberal Democrat leader.
Mr Clegg patted the teenage boy on the shoulder and continued to board his campaign bus, which was preparing to leave following the visit.
Nick Clegg said he has no plans for a new career after a member of the Question Time audience asked whether he had "plans for a new job next week when you become unemployed".
"Charming," he shot back. "No I don't."
The Lib Dem leader has insisted opinion polls that show him in danger of losing his Sheffield Hallam seat do not reflect the reality on the ground.
The Liberal Democrat leader has said he "very much enjoyed" tonight's leaders' Question Time.
While discussing possible coalition deals both Ed Miliband and David Cameron spoke about negotiations with Nick Clegg 'in a dark room.'
Responding to a question about the behind a scenes deal Mr Clegg said: "If either of them still think they're going to win a majority, they need to go lie down in that darkened room."
Nick Clegg is doing well as the third party leader on Question Time, ITV News Political Editor Tom Bradby says, but is getting less of a grilling from the audience.
This is like the most testing kind of X Factor. Nick Clegg doing quite well, so far, though he has had an easier ride than Ed M.
A few too many party lines, but he's generally making his points well.
Nick Clegg has said the Liberal Democrats will not enter a coalition with any party that wants to implement cuts to education.
The Lib Dem leader said both the Conservative and Labour policies on education "amount to a cut".
"I cannot be more clear with you. The Liberal Democrats will not go into any coalition, any government, we won't sign any coalition agreement if either of those parties insist on those cuts".
Nick Clegg has reiterated he "got it wrong" on tuition fees after the last election.
Asked how his party could be trusted after breaking their vow on tuition fees, Clegg retorted with a smile, "Nice, easy question to start".
"When you make a mistake in politics, just as in life, in politics just as in life, you can't do exactly what you want," the Lib Dem leader said.
"I was absolutely between a rock and a hard place five years ago on that particular policy," he added.
The three leaders have arrived for tonight's leaders' special Question Time in the final televised set-piece before the General Election.
David Cameron, Nick Clegg and Ed Miliband will not be on stage at the same time and will not debate directly with one another.
