Paul McKeever, Chairman of the Police Federation of England and Wales has told ITV News that police were being treated "less favourably" than others in the public sector with a 4 year pay-freeze, as well as cuts to pensions.
The PM's spokesman says today's strikes were "unnecessary" and that the "impact has been limited". He said borders managed without delays.
More than 20,000 off-duty police officers took to the streets today as they warned that Government cuts are putting public safety at risk.
The last time this many police officers hit the streets of London it was to quell the worst disturbances in England for a generation.
