Is there a way to remove only consecutive repetitions in an array? The UNIQUE function removes every other repietition irrespective of ther order

For example I have a matrix as follows

1 6
2 6
3 5
4 20
5 18
6 7
8 5
9 5
10 5
11 20
12 6

the matirx after suppression of consecutively repeated elements should be

1 6
3 5
4 20
5 18
6 7
8 5
11 20
12 6


In the consecutively repeates values i just need the first occurance (or any one of them). Is there a way to do this?

Any help is appreciated.

Thanks,
Nodal.
