Mr Robertson claimed Trident is an an "immoral, obscene and redundant weapons system" in his speech ahead of MPs voting on renewing Trident, which led to applause and cheers by his colleagues in the House of Commons.
He said the party had repeatedly won elections on its "explicitly anti-Trident manifesto".
Another Scottish independence referendum is fast approaching, SNP warns, after Westminster voted to renew Trident.

Nicola Sturgeon has accused the UK Government of "playing games" over Trident, ahead of MPs voting on the renewal of the nuclear deterrent.
