Should politicians be talking about immigration?
Labour is not treating immigration as "off limits"
Ahead of the final TV debate, Labour's Alan Johnson says pensioner Gillian Duffy was not bigoted to raise the topic of immigration and he was "really pleased Gordon made that clear". He went on to say that Mr Brown is under a lot of pressure and made a "dreadful mistake".
Elsewhere, Mr Clegg said he would focus on the problems with the banks and the "overheated housing market". While Conservative leader David Cameron has been discussing his party's plans to create a £200m cancer drugs fund.
Do you think immigration should be high on the political agenda? Should immigration be "off limits"? What immigration policies need to be discussed?
