So far there has been mixed reaction to The Chancellor joining Twitter. Former Deputy Leader of the Labour Party, @JohnPrescott welcomed Osborne with,
"So @George_Osborne gets 3,745 followers in just 18 minutes. If only he could get that kind of growth in the economy. Or indeed ANY growth."
Political blogger @GuidoFawkes tweeted,
"Quite a day for Osborne to join Digital Dave"
While political tweeter @beaubodor said,
"There won't be a second tweet from @George_Osborne until he's submitted his expenses for his first tweet."
Footballer @Joey7Barton chipped in with,
"Gonna follow @george_osborne to see if he actually tweets. If it turns out to be one of his servants, he'll be getting unfollowed sharpish!"
While comedian @davidschneider joked
"It's good you've joined Twitter, @George_Osborne, because if you're doing rubbish at your job, Twitter can really help you focus."
