I have tried spraying the leaves with diluted washing up liquid before spraying with Roundup to no avail. How can I get rid of it or stop it invading other plants in a small bed.

ANy plant will die if denied light, so you could cover it with black polythene until it dies.
Or use Roundup at a higher rate, 5% solution of Roundup Biactive should do the trick
