Transport for London staff from three transport unions are on strike this morning.
Backroom staff from the RMT, TSSA and Unite unions are staging a 24 hour walk-out in a dispute over pay and pensions.
Tube workers will begin a three day strike at 9pm this evening, in a row over ticket office closures and job losses.
It follows a two day walkout by RMT members, over the same dispute, last week.
London commuters will find out if First Great Western train workers are to go out on strike later today as the ballot closes for industrial action. Results are expected around lunchtime. The dispute is over dismissal procedures, agency working and zero hours contracts.
Last minute talks aimed at averting London Underground strike action will be held tomorrow. Members of the Rail, Maritime and Transport union and the Transport Salaried Staffs Association have voted to strike for 48 hours from 9pm Tuesday.
Tube bosses met union leaders last week with little sign of a breakthrough. Discussions will continue tomorrow. London Mayor Boris Johnson has offered to hold talks if the industrial action is called off. But unions say they will only meet with the Mayor if there are no preconditions of caveats.
Talks aimed at avoiding strike action on the underground will resume later today, as London Underground bosses and rail unions clash over planned ticket office closures.
The proposed action would see Tube workers stage two 48-hour walkouts on February 4 and 11.
There are now two rail unions backing the action, after the Transport Salaried Staffs Association (TSSA) voted yesterday to follow the Rail, Maritime and Transport Union (RMT) in supporting the strikes.
We will learn if London Underground staff will go on strike next month, when the ballot over industrial action closes today.1300 front line station staff could walk off the job in Febuary in the dispute over ticket office closures and job cuts.
We'll soon know whether London Underground staff will take strike action over proposed ticket office closures. The results of the RMT union's ballot is expected to be revealed later today.
It comes as the Transport Salaried Staffs Association asks its member whether they want to take action over the same issue. That ballot will close on January 27.
We want to reassure Londoners that the MPS has taken the necessary steps to ensure that in the event of strike action, our essential services to London will continue.
The MPS took the decision in November to give a 1% pay rise to all police staff. This is at the ceiling of the Government’s public sector pay policy and the pay increase was given without any strings attached to it. The PCS demands include a pay increase of up to 6%. The MPS is simply unable to meet this demand.
We have tried and tested continuity plans for all eventualities, including industrial action.
Union representatives have said they are discussing the possibility of co-ordinating strike action with the Fire Brigades Union, who are also due to walk out over New Years. The two strikes combined could see 7,500 workers walk out on one of the busiest days of the year.
In a ballot, 72.5% voted for strike action on a 23.1% turnout.
Thousands of civilian police staff - including 999 call handlers - are set to strike on New Year's Eve, the PCS union has said.
The planned strike would coincide with a walkout by London firefighters and could see around 7,500 civilian workers taking action on one of the busiest days of the year.
The strike was planned after a 1% pay rise was imposed by the Metropolitan Police last month, which is below inflation.
Police community support officers, 999 call handlers, detention officers in custody suites, and a range of administration and professional support staff are among those due to take action.
The Met said they were "confident" they have good contingency plans in place in the event of a strike.
