One way to stay in touch with what the likely candidates for Holborn and St Pancras and Islington South and Finsbury are up to is to follow them on Twitter. Twittelection has Twitter lists for each constituency Holborn and StP and Islington S.
I have set up a combined Kings Cross list so you can follow them all with one click. Please drop me a line with any issues or suggestions. I might extend the list in the future to include other local tweeters who speak for the parties (e.g. the local party branches).
There is a health warning though – some candidates barely use twitter others, shall we say, over use it.
