The clock is ticking on public consultation on Heathrow expansion plans.

The Department for Transport consultation on increasing flight numbers and building a third runway ends at midnight Wednesday.

Ahead of that, anti-noise protesters plan to converge on Parliament tomorrow.

Organised by the HACAN group and backed by a coalition of London councils, the protest will march to Central Hall, Westminster tomorrow to voice their opposition to Heathrow expansion plans.

Members of the rally are being urged to contact their MPs and lobby them by going to the Houses of Parliament.

The rally starts at 7pm and includes speakers from all parties, live music and videos.
