Lego sells out of women scientist role model sets

An all female set released by Lego has sold out after the firm responded to a letter from a seven-year-old girl who wrote to complain about the lack of women.

In January, Charlotte Benjamin wrote a letter to the Danish firm saying she was unhappy that male figures outnumbered female ones.

The new set sells in the US for $19.99 (£11.85) and comes with three women scientists, including a paleontologist, chemist and astronomer.
