Stange code in posts

Hi

I'm not sure if this is a theme issue or something else (in which case this topic ought to be moved) but I've developed a stage bit of code on my featured posts on the home page of my site using the Business Feature theme.

Interesting when I go to the actual post it disappears.

The code is {lang: ‘en-GB’} which shows up at the start of each of the posts.

You can see it here:

UPDATE

The culprit is the Google+1 plugin. There's an option to choose the language and whichever I select the code relevant to that language shows up. There's clearly a compatability issue with the Business Feature theme and the Google+1 plugin guys. Any ideas?
