Andy Murray has arrived at Buckingham Palace to receive his OBE from Prince William
- after revealing he feared he would be late due to a drugs test.
But Murray had earlier tweeted: 'In the middle of a drug test hahaha. I'm goin to be late!!!'
Prince William will be carrying out his first investiture ceremony as he stands in for the Queen.

The Scot became the first British man to win Wimbledon for 77 years this summer
but is currently sidelined after having back surgery.
