A spat over taxes has developed in the US presidential campaign, with president Barack Obama’s camp pushing Republican challenger Mitt Romney to reveal five years worth of tax returns.
The Democrat camp is implying wealthy businessman Romney may have something to hide about the amount of tax he has been paying.
The Republican candidate has already released his tax returns for the last two years, and now his running partner Wisconsin congressman Paul Ryan has done the same.
Despite refusing to provide the records, Romney says he has paid a tax rate of around 13 percent for the last 10 years, and has called the row a distraction.
Meanwhile Tampa in Florida prepares to host the Republican Party’s national convention, due to start on August 27.
During the convention Romney will officially accept the nomination to be the party’s presidential candidate in November’s election.
