David Cameron was the first in the political twitter race to offer congratulations to the Duke and Duchess of Cambridge after the announcement that Kate is pregnant.
Just minutes after St James's Palace announced the news, the prime minister tweeted: "I'm delighted by the news that the Duke and Duchess of Cambridge are expecting a baby. They will make wonderful parents."
Labour leader Ed Miliband was a close second and almost managed to squeeze 'one nation' into the posting: "This is wonderful news for the Duke and Duchess of Cambridge. The whole country will be thrilled.
"Justine and I offer Kate and William our warmest congratulations."
Clegg came in third with a delayed offering and posted:
First minister Alex Salmond put a Scottish spin on his good wishes, referring to the royal couple by their lesser known titles: "My warmest congratulations and sincere best wishes to the Earl and Countess of Strathearn on this wonderful news.
Everyone in Scotland will join me in wishing the couple the very best as they prepare for the birth of their first child."
Kate is expecting
President Obama also extended his congratulations from across the pond. A White House statement read: "On behalf of everyone here … beginning with the president and first lady we extend our congratulations to the Duke and Duchess of Cambridge on the welcome news we received from London that they are expecting their first child."
A spokeswoman for the University of St Andrews, where Kate and William met, said: "We are delighted for the couple and will be writing to them to offer our congratulations. They must be very pleased."
In a later comment to television cameras at 10 Downing Street, Mr Cameron reiterated his belief that the couple will make fantastic parents and said: "I'm sure people round the country will be celebrating with them tonight."
Mr Cameron confirmed he was informed of the news shortly before the public announcement.
"A little note came into a meeting I was having and I found it quite difficult to keep it to myself," he said.
