10 of the best pictures from the Asda protest march through Leeds

Protesters from across the country stopped in front of Asda House, the company's national headquarters, to shout 'shame on you' and 'no ifs, not buts, no Asda cuts'.

The GMB union, who organised the march, say staff have been told they will be sacked if they do not sign up to the new terms.

Asda is offering staff a higher wage in exchange for a new deal - called contract 6 - which will introduce unpaid breaks and a requirement to work over bank holidays.

The GMB are particularly concerned about the impact on single mums, workers who have multiple jobs and people with caring responsibilities, as they will have to be more flexible with their hours at shorter notice.
