using unique function on column 2 and keep first col

Hi sorry for this simple question

G =

     1     2
     1     3
     1     5
     5    10
     6    10
     8    13
     9    13
    10    13
    12    13
    13    14
unique(G(:,2));

result :

ans =

     2
     3
     5
    10
    13
    14

i want it to bring the first column with it like this and save it in same array or another new array

G =

     1     2
     1     3
     1     5
     5    10
     8    13
    13    14

Thanks
