The match at Wembley Stadium will take place on Saturday 15 May.
It will be the 10th game between the clubs in the FA Cup but the first at the final stage. Leicester were last at this concluding stage of the competition in 1969. Chelsea contested three of the last four finals.
This year’s final will be broadcast live in the UK on BBC One, BBC iPlayer, BT Sport 1 HD and BT Sport Ultimate.
Following the traditional coin toss, Chelsea’s outfield players will be able to wear our home kit of blue shirts, blue shorts and white socks, and our goalkeeper will be in all grey. Leicester’s outfield players will wear all maroon, with their goalkeeper in all green.
