Nick Clegg was invited inside a Sheffield voter’s home to watch the announcement about today’s royal birth.
The Liberal Democrat leader is out canvassing today ahead of Thursday’s General Election.
He said he was invited into a voter’s house to watch the announcement on TV.
Following the announcement, he came outside to pass on the news to reporters.
The Lib Dem leader tweeted shortly afterwards: “On the doorstep in Sheffield. Thanks to the kind constituents who invited me in to see the great royal baby news being announced on their TV.”
Mr Clegg said that he and his wife Miriam wished them “all the best as their family grows”.
Other politicians have also sent their congratulations to the Duke and Duchess of Cambridge on the birth of their new daughter this morning.
“I’m absolutely delighted for them,” David Cameron said on Twitter.
“This is great news and an exciting time not only for them, but also Prince George.”
Scotland’s First Minister Nicola Sturgeon said she was “delighted” at the news and offered her “warmest congratulations” to the royal couple.
Labour leader Ed Miliband tweeted: “Congratulations to the Duke and Duchess on the birth of their daughter. Wishing them lots of joy and happiness - and hopefully some sleep!”
