These are the online petitions that get discussed by the government if they get a certain abound of signatures. I think it is 5000.
The e-petition I have been sent is all about Intra Company Transfers (ICTs). More specifically how workers brought to the UK on ICTs, often IT workers on projects in the UK, are paid a large portion of salary in expenses, which is not taxable.
In the end it makes the offshore worker much cheaper than the UK worker, hence making UK IT professionals uncompetitive.
The person that put the e-petition in linked to an article I wrote about this which should help explain.
The e-petition, which can be logged into here, asks for people's views on whether the HMRC should tax expenses paid to ICTs. If you have a view why not fill it in?
