PMQs: Cameron and Robertson on Scotland Bill powers
The SNP's Angus Roberson questioned the prime minister about pledges of more powers made during the Scottish referendum and asked why these were not honoured in the government's Scotland Bill.
The prime minister challenged the SNP to use its existing powers and put up taxes and spend money if it was not happy.
And using a three-letter phrase, which has cruder connotations to some people, David Cameron claimed that "full fiscal autonomy has now become FFS - full fiscal shambles".
