British singer Rita Ora has axed two concerts after falling sick with a throat infection.

The R.I.P. hitmaker was due to perform at a racecourse in Merseyside, England on Friday evening (09Aug13) before heading to Zofingen, Switzerland for a gig on Sunday (11Aug13).

However, she has been forced to cancel both performances after coming down with a throat and chest illness and has apologised to fans for the change of plans.

In a series of posts on, Ora writes, "I would never do this unless I physically had too (sic) and in this situation I unfortunately do. I am so so sorry for cancelling my shows this weekend. I've never and will never not perform unless I physically can't put on a good show for you. I have a bad infection in the throat and chest. I am so sorry and as soon as I get better I will make it up to you. I promise. I love you. Rita."
