Lloyds Bank has been accused of religious discrimination after offering free overdraft accounts to Muslims.
The bank sent customers a booklet this month explaining new charges.
While many will have to pay up to £80 a month if they go into the red, Muslims were told they would escape the charges. The document said: "We are removing the monthly overdraft management fee of £6 from our Islamic Account, Islamic Student Account and Islamic Graduate Account. So, if you use an unplanned overdraft on these accounts, there won't be any charges."
