Los Campesinos! rocker Ellen Waddell has announced she's leaving the group following a final show next week (15Dec12).

The bass player has appeared on all three of the Welsh band's albums.

She took to the act's website to let fans know of her departure, writing, "It is with a sad face I have to report that I am leaving Los Campesinos!"

And she admits next week's swansong gig will be a tough one, adding, "The show on the 15th of December in London will be my last, and I shall spend it struggling not to cry. Please don't point out my tears if you come along. Simply pretend it is eye sweat."

She does not expand on the reasons behind her decision to leave, but it does not appear to be due to any kind of falling out with her bandmates.

She adds, "Over the last seven years I have been blessed, not by God, because he doesn't exist, but with opportunities and a life I will not fully appreciate until I am about forty-five. I will look back at old photos of the band, with our smooth skin and questionable hair, and go 'f**k me. That was mental'."
