Cameron in a pickle over Scotland promises

In order to swing the Scots' vote last week away from an ever-more popular independence campaign, Cameron, together with the leaders of Labour and the Liberal-Democrats, pledged to keep the funding scheme and give Scotland further powers as long as it stays within the United Kingdom.

The referendum was won by the unionist camp, but Cameron has since faced an avalanche of criticism. Apart from his own backbenchers who want more powers for English MPs, the prime minister is also under fire from the Labour opposition, which says it has only subscribed to Scottish devolution.

Labour leader Ed Miliband on Sunday said the three-party deal only concerned Scotland, not England or Wales.

"I'm open to the idea of greater scrutiny of legislation by English MPs. But we can't do it in a back of the envelope, fag packet way," Miliband said.

Scottish leader Alex Salmond on Sunday said his people were tricked into voting No, as Cameron's plans will fail amid inner-party bickering.

"It is the people who were persuaded to vote 'No' who were misled, who were gulled, who were tricked effectively," Salmond told BBC.

However, Downing Street insisted that Cameron would honour his promise to devolve powers to Scotland with “no ifs, no buts".

“The three pro-Union parties have made commitments on further powers for the Scottish Parliament and we have set out a clear timetable to do this. This Government has delivered on devolution and we will do so again in the next parliament,” the Downing Street statement added.
