Video: Tom Daley, boyfriend Dustin Lance Black offer double date for charity

Olympic diver Tom Daley and his partner Dustin Lance Black are offering fans the chance to go on a double date with them in a bid to raise money for charity.

The couple went public with their relationship shortly after Daley revealed that he is gay last year.

This week, the pair have released a video offering the chance for people to join them on a date in London with all proceeds going to the UK's Brain Tumour Charity and US gay rights organisation The Human Rights Campaign.

Daley opted to fundraise for the cancer charity after his father Robert died back in 2011 following a five-year battle against the disease.
