What the hell is going on here

Installing a new light fitting. I thought it would be as simple as blue to blue & brow to brown but there are so many wires coming out I physically cannot get them all in the connection and one of the blue wires has a brown end which I assume is for the switch? No local electrician can get out to me until after Christmas as I live in the middle of nowhere. Can anyone help with this, thanks in advance all!

Happy holidays
