Deputy prime minister Nick Clegg has suggested in an interview with the Guardian that the wealthiest people in the country could be asked to pay more tax for a limited period.
He said fairness was essential to making austerity measures a success and that to remain cohesive and prosperous as a society those of considerable wealth should contribute more as the country fights an "economic war".
The proposed time-limited contribution from the richest in society moves beyond his party's current policy for a “mansion tax”.
