Mis-aligned part

Hi,

This is probably an easy question, but  have a part which has become 'out of axis' so to speak (even if I click one of the set views at the top, the part is still at an angle). I'm not sure how this happened, I must have done something. As you can imagine, it is making engineering drawings look very bad.

Is there a way which I can re-align the part back to the axes?

thanks!
