Prime Minister Aigas Kalvitis asked Minister of Transport Ainars Slesers to resign, which the minister did. The reason was that Slesers "had lost the public trust" because of his alleged involvement in a bribery scandal surrounding the election of the mayor of Jurmala, a Riga suburb by the seaside. Transcripts of an eavesdropped telephone conversation seem to indicate that Slesers was aware of an attempt to bribe a city council member to vote for the candidate of Sleser's Latvian First Party. See the earlier item about "the biggest cretin". Slesers has denied any wrongdoing.
I won't go into the bizarre and sordid politics of the whole affair, but will instead mention a few things that happened on "his watch" as MoT.
Most of the events under Slesers were on the "physical" transport side. Ryanair and Easyjet were brought to Riga, opening low cost travel to and from Latvia to new groups of people, from Latvian middle class families to boozy British bachelor party groups (they spend their money here, fine with that).
In telecommunications, Slesers was running the ministry when the third UMTS/GSM licence was auctioned to Bite Group. This has been a major stimulus to competition for mobile voice and data services. His time as minister also saw the implementation of number portability which has generated a "churn" of around 9000 mobile customers and 1000 fixed line users. With more than 1.8 million mobile and 600 000 fixed line users, this was less than trivial and had nothing to do with who was MoT.
Slesers seems to have a fairly competant team of professionals in the MoT under the Communications Department, who have their fingers on the pulse of most things. However, the market is mature enough to move ahead without much prodding from the government and we will see such things as very fast and affordable broadband, fast mobile internet, VOIP as the default voice platform for broadband users, IP TV, user-generated TV, HDTV etc. etc., all coming through a fast fixed or mobile link regardless of who is the new MoT. Rumor has it that the post may be filled until the elections in October by Latvian First Party (LPP)parliamentary whip Juris Lujans. That is, unless the LPP leaves the government and brings the whole shithouse down. But that is unlikely.
