Overall Conclusion

An example of a conclusion would be:

Source B is the most reliable as it was published by a Government Department who have a responsibility to be accurate and as up to date as possible when it provides information for the public.

Source C is less reliable as it is from a blog written by someone who admits on his home page that he is a supporter of the Labour Party so he is likely to take a view that is biased.

Source A is probably the least reliable as it is from the Daily Mail which is not only biased towards the Conservative Party the article was written ten years ago and is therefore out of date.
