Your chance to quiz Boris as he opens up City Hall

Boris Johnson will use tomorrow's annual State of London debate to reaffirm his pledge to open up City Hall to the public and put accountability at the heart of his reign.

The Mayor will commit to ensuring Londoners know how every penny of their money is spent as he drives through efficency savings to freeze the Greater London Authority council tax for the first time since it was set up nine years ago.

Every resident in the capital is invited to the free event at the QEII Conference Centre in Westminster to raise questions with the Mayor and other senior figures. Mr Johnson will highlight that he has improved transparency and drawn a line under the issues that dogged Ken Livingstone. Measures include publishing job description and salary of every deputy mayor and adviser on the GLA website. Mayoral advisers also have their interests published and the GLA publishes details of all payments over £1,000.

Mr Johnson will say that by focusing on doing fewer things better, he has found £104.4 million of savings this year without impacting on key services, such as the delivery of 440 uniformed police on buses.

In his speech, Mr Johnson will say: "I promised that I would open City Hall up to scrutiny and that is what I have done. By holding regular public meetings and increasing the number of People's Question Time events, my administration has given Londoners the opportunity to directly quiz me and my team."

He will point out that his administration has brought in a £3 billion economic recovery plan to help tackle the financial downturn and highlight the new Time For Action plan to address youth crime. The Mayor will also seek to dispel doubts over a £5 billion housing strategy to deliver 50,000 affordable homes.

He will outline his transport plans to push through Crossrail and a "£111 million cycling revolution".

● The State of London Debate takes place from 10am to 3pm tomorrow.
