'This is a momentous development in the long journey of empowering our women.
'The bill that is going to be passed today is a historic step forward, a giant step forward in strengthening the process of emancipation (of women),' he said , drawing thunderous applause.
Speaking extempore, Manmohan Singh said that despite the many progress achieved by women in India, 'we have also to recognise that ... our women have faced enormous difficulties...'
'Our women faced discrimination at home, there is domestic violence, they face discrimination in equal access to education, healthcare, there are all these things. All these things have to end if India were to realise its full potential.'
'What we are going to enact today is a small token of homage to the sacrifices our women have made in nation building, in the freedom struggle, in all other nation building activities.'
There are currently 59 members in the 545-member Lok Sabha. The new rules will set a floor of 181 women MPs. This method of a national quota will see all women constituency contests between the different political parties in chosen constituencies, which may rotate over time.
In the highly unlikely event that Britain were to adopt as radical a gender equality measure as India, the number of women in the House of Commons would rise from the current 126 to at least 216 women MPs. The number of women in the next House of Commons looks likely to be broadly similar to the current number. It could be marginally up, though the number of women MPs would probably fall if the Conservatives were to win a large majority. (There would be around 61 Tory women if the party won a majority of 2, yet only around 69 Tory women MPs if the party won a majority of 100).
The Bill would amend the Indian Constitution, and so needs two-thirds support in both houses of Parliament and to be carried by state legislatures, but now seems very likely to be carried. The government had timed the vote to be held on International Women's Day yesterday, but was postponed due to protests from minor parties, who wanted the bill to go further. Seven members of Parliament were suspended for their protests.
The issue of quotas is controversial. Previous attempts to pass a similar Bill had failed several times over the last 15 years.
What is striking, especially from a British and European perspective, about the 2010 debate is how each of the major parties has decided that being seen to oppose the principle of the Bill could be politically dangerous with women voters.
