MPs have another chance this afternoon to debate the merits of the controversial £43bn High Speed 2 (HS2) scheme.
The hybrid bill to allow phase one of the rail link is receiving its second reading in Parliament today.
Transport secretary Patrick McLoughlin told MPs all alternatives to the scheme had been considered and a huge amount of impact assessment had been carried out.
A vote will follow later. Reports suggest there may be a small rebellion by some Conservative MPs but a large majority in favour of the legislation is expected.
The bill is effectively the planning application for the 225km of route required for the London-to-Birmingham section of the scheme, and will give the government the powers to construct and operate the railway.
Project promoter HS2 Ltd is aiming to start construction of the line in 2016/17. It is due to open in 2026.
Do you think HS2 will begin within three years as planned? Give your views in the comments box below.
