BMI - do you still get tier points?

Am confused still about the changes at BMI ... but, I have a contract coming up with some European travel. In the past my company has always made me fly BA but do you still get miles and tier points (if in business on a route BMI still offers business on) with BMI? If so, I'll engineer a switch ...
