He says a trial of virtual committee hearings had been successful - and he wants to extend the idea.He has asked officials "to investigate how they would apply similar technology" for use in the Commons chamber.In a letter to Commons leader Jacob Rees-Mogg, Sir Lindsay asked if he would "make representations to government" to enable the Commons to legislate, scrutinise and represent constituents in this way.

Further extension?He also urged Mr Rees-Mogg to indicate "as early as feasibly possible" if the Commons will return after its longer Easter recess on 21 April - or whether it will be extended further.

Sir Lindsay said "numerous" MPs had raised issues with him about how Parliamentary scrutiny could continue during the crisis.

"Once the House returns, if we are still in the grip of the crisis where the physical presence of members, or too many Members, in the Palace is not appropriate, I am keen that they should be able to participate in key Parliamentary proceedings virtually, for example, oral questions, urgent questions, statements,' he said.

He said it would be up to the government to authorise any changes, "as I cannot do so under my own authority".

'Distressed constituents'Sir Lindsay also asked if it would be possible for the government to set up a forum of MPs during this recess, possibly via select committee chairs, who could quiz senior government representatives at set times on different days "about how things work and how they can be improved".

"MPs are being swamped right now with questions and case work from distressed constituents who need answers," he said.

"Responses cannot wait for the House to sit again."It comes after more than 100 MPs signed an open letter calling for the creation of a digital Parliament.The group of MPs from Labour, the Lib Dems and the SNP say that during the "exceptional circumstances" of the coronavirus outbreak "Parliament must work exceptionally".In the letter to the Clerk of the House of Commons, the MPs said "it is clear that Westminster is not a safe working environment and cannot be made so whilst including a representative number of MPs".On Tuesday, Prime Minister Boris Johnson, who is self-isolating in Downing Street after being diagnosed with coronavirus, chaired the first virtual cabinet meeting, with members of his ministerial team dialling in via a video conferencing system.Virtual SeneddEarlier on Wednesday, The Welsh Assembly - or the Senedd - claimed to be the first major democratic institution in the UK to meet remotely.Members of used Zoom video conferencing to meet virtually from across Wales for the weekly plenary session, which usually takes place in Cardiff.
