The happy prince: Prince William greets well-wishers along The Mall ahead of his weddingThere's no room left near the Abbey for people wanting to get the first glimpse of the married couple
Camilla went out to meet people waiting outside Clarence House earlier in the day
Prince William delighted thousands of well-wishers in The Mall last night as he staged an impromptu walkabout.
Joined by his brother Harry, the beaming prince stunned die-hard fans when he appeared from Clarence House at about 8.30pm to thank them for their support.
A few burst into tears and a sea of hands rose up, desperate for the chance to shake hands with the prince and to wish him luck before the big day.
Best man: Prince Harry joined his brother on the stroll near Clarence HouseDressed casually in a pale shirt, black jumper and chinos, he looked relaxed as he cracked jokes with the crowd, echoing his mother Diana’s easy nature with the adoring public.
He paid particular attention to the children who squeezed forward to peer over the barrier at the tall prince.
His brother Harry kept his distance so as not to detract attention from the man of the hour – so much so that television cameras did not even notice he was there until he strolled back into Clarence House.
