Protesters occupy Fortnum & Mason store in Piccadilly
More than 250,000 people have attended a march and rally in central London against public spending cuts.
The main rally passed off peacefully but splinter groups have staged separate demonstrations.
A sit-in organised by the campaign group UK Uncut took place at Fortnum & Mason department store in Piccadilly.
The group has previously mounted protests against tax avoidance measures by big businesses.
