Boys receive more expensive gifts at Christmas with parents spending nearly £100 more on their sons than their daughters, research suggests.
Parents also said Christmas presents could cause arguments
The Woolworths online poll showed boys request more costly electronic goods as presents, and are better at pestering their parents to buy them.
It found girls prefer cheaper presents such as dolls and trinkets.
Some 3,500 parents with children under 16 were surveyed by the retailer in the first week of November.
The poll found parents spend an average of £223 on presents for boys, compared with just £127 for girls.
The top five boys' toys for Christmas add up to £428.95, but just £162.45 for girls.
Woolworths' head of toys Jo Hall said boys presents were more expensive because they "involve more technology".
"Boys are more likely to want to add to their computer game collection or have the latest gadget, all of which are more expensive than the latest hair accessory or Barbie or Bratz doll," she said.
Parents also said presents were a big cause of arguments between siblings on Christmas Day, especially if one has more gifts to open than another.
