Guido is very much enjoying the growth of @eyespymp – in just a couple of days it has garnered nearly 1500 followers and is starting to bear more fruit than even its predecessor. Guido hears that some MPs are up in arms about invasion of their privacy and that hacks are chortling away. Though people are often too quick to dismiss her, Nadine was the first to clock that the Lobby might not be laughing for long: “The hacks are going to realise that @eyespymp may yet bite them on the bum!” And indeed the penny is starting to drop.

Yvettte Cooper was outed earlier lunching with Polly Toynbee in the Atrium restaurant on Millbank. Whatever tit-bit she was trying to plant in tomorrow’s Guardian has had its source well and truly blown. Former hack-pack totty turned yummy-mummy Gaby Hinsliff* has had a moment of enlightenment: “wow. @eyespymp is going to make it hard for lobby journalists to protect sources. start looking for more obscure lunch venues.” Lazy hacks might have to actually trundle even further than Shepherd’s at this rate.

*Is it just Guido that thinks Gaby might be missing the cut and thrust of Westminster life? She is tweeting away all day and he has seen her byline more times since she went to live a life of domestic rural bliss than when she was working for the Observer. Poor Mr Hinsliff must be close to a “it’s Twitter or me” moment.
