£5.6 million is enough to keep it at the top of the tree which brings its total UK gross to £25 million after 10 days in cinemas.
Repeating last weeks top 2 Alving and the Chipmunks The Road Chip hangs on in the runner up spot for a second week.
Highest new film of the week is the female let comedy How To Be Single staring Dakota Johnson and Rebel Wilson.
The valentines day/date movie has an appeal for men but has a strong female appeal in direct competition to Deadpool, although that film does have a strong female appeal.

The only other new film on the top 10 is Triple 9 at number 6.
