A Spanish judge has summoned Barcelona footballer Lionel Messi to appear in court on 17 September over tax fraud allegations, reports BBC News. The 25-year-old Argentine, who has four times been named World Player of the Year, and his father are accused of defrauding the Spanish authorities of more than 4m euros (£3.4m).

They are suspected of using companies abroad - in Belize and Uruguay - to sell the rights to use Messi's image.

They both deny the allegations.

Messi's net salary from Barcelona is said to be about 16m euros a year, making him one of the world's most highly-paid sportspeople.
